Title:
DUAL-LOOP PREDICTIVE CONTROL-BASED SWITCHING TYPE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/019555
Kind Code:
A1
Abstract:
A dual-loop predictive control-based switching type control method, relating to the fields of power electronic conversion technology and industrial control. The method is based on dual-loop predictive control, and dead-beat control is used for outer-loop control. A switching type control method is used for inner-loop control, wherein when a system is in a steady state, the stability accuracy of the system is ensured by means of the dead-beat control, and a fixed switching frequency is achieved; when the system is in a transient state, it is ensured that the system is quickly transitioned to the steady state by switching to finite control set model predictive control. The method has the respective advantages of dead-beat control and finite control set model predictive control; moreover, dead-beat control is used for an outer loop, and thus, the overall performance of the system can be improved, and the operating requirements of a power electronic system are met.
