Switching control method based on dual-loop predictive control

摘要

The present invention relates to a switching control method based on dual-loop predictive control, and belongs to the field of power electronics conversion technology and industrial control. The method uses deadbeat control for outer loop control based on dual loop predictive control. The switching control method is used for the inner loop control, and when the system is in a steady state, deadbeat control is used to ensure the accuracy of the steady state of the system and realize a constant switching frequency, and the system is in a transient state. If, then switching to finite control set model predictive control ensures that the system quickly transitions to steady state. This method combines the respective advantages of two types of control, deadbeat and finite control set model prediction, and by using deadbeat control in the outer loop, the performance of the entire system can be significantly improved and Meet the work demands of the electronics system.
