摘要
Abstract
In the optimal duty cycle model predictive control strategy of permanent magnet synchronous motor, the voltage vector direction is fixed and the range of optional vectors are limited, and only the quadrature component of current is controlled by using a deadbeat solution, so the current still has large ripples. In this paper, a three-vector-based model predictive current control strategy is proposed. In this method, three basic voltage vectors are equivalent to synthesize a expected voltage vector in each sector, and six expected voltage vectors in six sectors are used as candidate voltage vectors, which can cover any direction and any amplitude. In order to achieve the deadbeat control of the direct and quadrature current components simultaneously, the deadbeat principle is used to calculate the vector duration in this paper. The strategy can reduce the current ripples effectively, and improve the steady-state performance. Experimental results demonstrate the feasibility and effectiveness of the proposed strategy.关键词
