As shown in the figure, the control device 1 for controlling a target device according to a feedback signal may include control器 11 and feedback circuit 12.

The controller 11 can be connected to the target device T, and can input a control signal CS to the target device T to control the target device T to output a physical quantity. In an embodiment, the controller may be a central processing unit or other similar components; a control signal CS can be a pulse width modulation (PWM) signal or various other digital signals.

In contrast, when the controller 11 judges that the high level interval of the feedback signal FS is lower than a desired high level interval, it indicates that the control signal CS is lower than the bearing capacity of the target device T; at this time, although the target device T will not be overloaded due to overload It is damaged, but its performance is low at this time; therefore, the controller 11 can adjust the control signal CS to make the control signal CS track the feedback signal FS; in other words, the controller 11 can increase the high level interval of the control signal CS to make the feedback The high level range of the signal FS can be close to the expected high level range.

It is worth mentioning that many self-learning mechanisms applied to artificial intelligence systems have been developed; however, since these self-learning mechanisms are still in the development stage, there are still many technical bottlenecks to be overcome, resulting in further improvements in their effectiveness. . On the contrary, according to the embodiment of the present invention, the control device that controls the target device according to the feedback signal enables the control signal to track the feedback signal. Through the special self-learning mechanism described above, the target device can be properly controlled, so that the target device can Achieve the best performance without exceeding its capacity.

In addition, in the existing self-learning mechanisms, each self-learning mechanism can only be applied to a specific application and cannot be widely used in various different fields, so its application is greatly limited. On the contrary, according to the embodiment of the present invention, the control device that controls the target device according to the feedback signal can be applied to various different applications, and therefore has wider application.

In addition, according to the embodiment of the present invention, the control device for controlling the target device according to the feedback signal can be implemented without a complicated hardware structure, so the desired effect can be achieved without significantly increasing the cost. As can be seen from the above, the present invention has progressive patent requirements.

Please refer to FIG. 3, FIG. 4A to FIG. 4B, FIG. 5A to FIG. 5B, and FIG. 6, which are block diagrams of a second embodiment of a control device for controlling a target device according to a feedback signal according to the present invention. And a schematic diagram, this embodiment illustrates how to control the charging device T ′ by the control device 1 that controls the target device according to the feedback signal; as shown in the figure, the control device 1 that controls the target device according to the feedback signal may include the controller 11 And feedback circuit 12.

The charging device T 'may include a power supply P and a battery B.

The controller 11 can be connected to the power supply P, and can input a control signal CS to the power supply P to control the physical quantity, that is, current, that the power supply P inputs to the battery B. In this embodiment, the control signal CS may be The pulse width modulation (PWM) signal, and the current input from the power supply P to the battery B can be adjusted by changing the duty cycle of the control signal CS.

The feedback circuit 12 can receive the feedback signal FS corresponding to the current input from the power supply P to the battery B by the battery B, and can transmit the feedback signal FS to the controller 11.

The controller 11 can execute a self-learning mechanism to adaptively adjust the control signal CS to control the current input from the power supply P to the battery B, so that the battery B can achieve the best charging efficiency without exceeding its capacity.

The controller 11 may compare the low level interval of the feedback signal FS with a desired low level interval to determine whether the control signal CS exceeds the capacity of the battery B. When the duty cycle of the control signal CS input by the controller 11 is 20% (as shown in FIG. 4A), the low level range of the feedback signal FS exceeds the expected low level range (as shown in FIG. 4B), which indicates control The signal CS far exceeds the capacity of battery B; at this time, battery B can achieve higher charging efficiency, but may be damaged due to overload. Therefore, the controller 11 can continuously adjust the control signal CS so that the control signal CS tracks the feedback signal FS to reduce the current input from the power supply P to the battery B, thereby reducing the low level interval of the feedback signal FS.

In contrast, when the duty cycle of the control signal CS input by the controller 11 is 70% (as shown in FIG. 5A), the high level interval of the feedback signal FS is lower than the expected high level interval (as shown in FIG. 5B). , It means that the control signal CS is lower than the capacity of battery B. At this time, although battery B will not be damaged due to overload, the charging efficiency is relatively low. Therefore, the controller 11 can continuously adjust the control signal CS so that the control signal CS tracks the feedback signal FS to increase the current input from the power supply P to the battery B, thereby increasing the high level interval of the feedback signal FS.

The controller 11 can repeatedly adjust the control signal CS to optimize the control signal CS, so that the control signal CS can continuously track the feedback signal FS; finally, the control signal CS can oscillate within a range and reach a convergence state.

As shown in FIG. 6, through the self-learning mechanism described above, the controller 11 enables the control signal CS to continuously track the feedback signal FS. This can find out that the optimal duty cycle of the control signal CS is 45% -55%. It can oscillate in this interval to achieve a convergence state, so that the load index of the feedback signal FS can continue to oscillate in an ideal interval; in this way, battery B can achieve the highest charging efficiency and will not be damaged due to overload. .

In addition, the control device 1 for controlling the target device according to the feedback signal can be applied not only to the charging device T ', but also to various other applications; for example, the control device 1 for controlling the target device according to the feedback signal can be applied to a manual device. The intelligent robot makes it capable of self-learning; in one embodiment, the control device 1 that controls the target device according to the feedback signal can be connected to the robot's arm; when the robot wants to take an object through its arm, according to the feedback The control device 1 of the signal control target device can sense the force of the object by the sensor (ie, the feedback circuit), and find out the best holding force through the self-learning mechanism described above, so that the robot can stably take the object , And the body will not be damaged due to the excessive holding force of the robot.

Of course, the above is only an example, and the components of the control device 1 and the cooperative relationship of the control device 1 according to the feedback signal may be changed according to actual needs, and the present invention is not limited thereto.

In summary, according to the embodiment of the present invention, the control device that controls the target device according to the feedback signal enables the control signal to track the feedback signal. Through the above-mentioned special self-learning mechanism, the target device can be properly controlled to make the target device It can achieve the best performance without exceeding its capacity.
