Application of fuzzy membership algorithm in dynamic voltage regulation control

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 its discontinuous system make it have 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 show 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, improve the regulation accuracy of the AC voltage regulator. It can be seen from the experiment results that the regulation accuracy of the system after optimizing the switching rule is 5-10 times preset, which proves the effectiveness of the improvement.
