Research Of Non-Contact Compensation Ac Voltage Regulator Based On Fuzzy Strategy

The non-contact compensation type AC voltage regulator possesses the advantages of small size, high efficiency, low cost, etc. due to its simple structure and convenient control, and is widely used in the field of AC voltage regulation technology field. However, the non-contact compensation type AC voltage regulator belongs to the class of voltage regulation. And the characteristics of the discontinuous system has the disadvantages of low control precision and weak system reliability. Fuzzy control strategy, through fuzzification and approximate reasoning, can solve the problem of such discontinuous control systems. Some research work shows that using the fuzzy membership strategy to optimize the switching rules of the control system can greatly improve the control precision of the voltage regulation, that is, can improve the regulation accuracy of the AC voltage regulator. The experiment results verify that the regulation accuracy of the system after optimizing the switching rule is 5-10 times pre-set, which proves the effectiveness of the improvement.
