Element in the domain of table 1 class of pollution S is for the degree of membership of fuzzy set
Element in the domain of grade ES under the table 2 pollutant levels changing value is for the degree of membership of fuzzy set
Element in the domain of table 3 controlled quentity controlled variable U is for the degree of membership of fuzzy set
Control law determination module 303c is used for setting up control rule base according to the grade under the class of pollution and the pollutant levels changing value, and obtains control rule table according to the control rule base of setting up and table 1, table 2, and is as shown in table 4.
In addition, control law determination module 303c also can further obtain control rule table according to table 3.
Control rule table can be the grade under the class of pollution under the pollutant levels, the pollutant levels changing value and the mapping table of controlled quentity controlled variable.
Control rule base is used for the storage control law, and control law can also be rule of thumb summed up with expert knowledge library and drawn.It can also consider determines contamination level S, the affiliated grade ES of pollutant levels changing value, obtain some control laws, if for example wherein control law can be that to be 7 grades (be that the class of pollution is high to the class of pollution, corresponding pollution level is high), then the grade ES under the pollutant levels changing value is arbitrary value, then controlled quentity controlled variable to be set as 3(namely high-grade).If one control law can be that grade ES under the pollutant levels changing value is greater than a threshold value (for example 5), be 6 or 7(be high-grade, that is to say, pollutant levels thicken suddenly), the class of pollution under the pollutant levels is more than the first estate, for example (0 grade can represent pollution-free) more than 0 grade then is set as controlled quentity controlled variable the first preset value (being numerical value 3).This rule is proactive, although the grade under the current pollutant levels is 1 or other values, might be not high, the grade under the pollutant levels changing value uprises suddenly, can foresee that next constantly pollutant levels might increase suddenly, be set as 3 with controlled quentity controlled variable this moment.
Controlled quentity controlled variable can comprise respectively 3(the 3rd grade in the corresponding control rule table of the first preset value, the second preset value, the 3rd preset value and the 4th preset value according to actual needs), 2(the 2nd grade), 1(the 1st grade), 0(the 0th grade).And it is the highest that the 3rd grade represents that the degree of air cleaning is carried out in needs control, and the 2nd grade, the 1st grade, the 0th grade represent that needs control the degree of carrying out air cleaning and reduce successively.The concrete numerical value of controlled quentity controlled variable can be set according to actual needs, for example, can be set as any number such as letter or number.The implication of the concrete numerical value representative of controlled quentity controlled variable also can be carried out respective settings in advance in fuzzy controller.
