Fuzzy variable based step-size self-optimizing control implementing to a resonance liquid reactor

It is difficult to model a liquid resonance controlling system when there are different materials, different capacity of the container, different liquid density and so on in the system. In order to realize resonance of these liquids in the container, a self-optimizing control method of the level of the liquid is suggested. Meanwhile in order to improve control precision and decrease response time, the step-size of self-optimizing of frequency of acceleration is changed by fuzzy control strategy in the control system. According to self-optimizing method, the fuzzy control rule sheet is put forward. The results of experiment show the suggested methods can implement resonance of liquid in the container automatically.
