Abstract

The invention provides a voltage transformation circuit control system and method based on automatic optimizing model-free controller. The system comprises a virtual model-free controller with a compensation factor, a performance determining module, and a performance optimizing module. The virtual model-free controller with the compensation factor is used for establishing a control rate output module with an output compensation factor. The performance determining module is used for determining an object function according to output voltage required to be achieved by a voltage transformation circuit, and setting an upper limit of the number of performance optimizing times, and controlling the number of optimizing times of the performance optimizing module according to whether the voltage transformation circuit reaches optimal performance at present. The performance optimizing module is used for optimizing the step length sequence of the control rate, the weight parameter of the control rate, and an output rate compensation factor coefficient by using an optimization algorithm so as to obtain the optimized step length sequence of the control rate, the optimized weight parameter of the control rate, and the optimized output rate compensation factor coefficient.
