In parallel fuzzy pid Composite controller design , The fuzzy control part and must be adjusted in time according to the deviation pid control

Proportion of parts , And this more complex control strategy is beneficial use universal through Of simulink model block yes very difficult real present Of ) Mining use s Letter Count Come on Explain " This problem , First of all, based on m Language writing s Function to realize fuzzy control and pid Control the adjustment of proportion , And then in simulink Call in the simulation environment s Function program , So as to establish the fuzzy pid Simulation model of compound control system , This method has simple simulation model and easy programming , It is convenient to realize various Ministry branch the Occupy Than example along with partial Bad Big Small Of transfer whole , from and can enough take have to more good Of control system effect fruit )

key word ： fuzzy control ;pid control ;simulink;s function

With the increasing complexity of the controlled object , The adoption is based on fine indeed model The traditional control method of type A is often difficult to achieve satisfactory control

effect ) Fuzzy control has an accurate number independent of the controlled object Learn models 、 Good dynamic performance and other advantages , At present, it has been in engineering practice

It has been widely used , benefit use model paste control system dynamic state Good performance and pid The control steady-state performance is good Of , spot , people People Various compound controllers are designed , Parallel type model paste pid control system The device is one of them , In parallel fuzzy pid control system device in , model paste control system Ministry branch and pid The proportion of the action size of the control part is important to the controller Has a great impact on the performance of , For this more complex control System , Use pu through Of simulink model block yes nothing Law take build Imitation really model Type , The author is in Medium Shao and United type model paste pid control system device and s Function based on , use m Language writing s function , however In the after simulink Call in the simulation environment s Function program , establish Fuzzy pid Simulation model of control system , convenient The earth real present 了 Adjust the proportion of the two controls with the size of the deviation )
