A Universal Method to Expand Candidate Voltage Vectors and Fast Determine Optimal Voltage Vector of Deadbeat Control for PMSM
摘要
Abstract
[Objective]In the deadbeat control of surface-mounted permanent magnet synchronous motor(SPMSM),the contradiction between the number of candidate voltage vectors and the computational burden limits performance optimization.This paper aims to propose a solution that balances control accuracy and real-time performance.[Methods]Taking SPMSM as an example,the following methods were proposed:(1)The n-th order subdivision method of the inscribed circle of the voltage vector hexagon was used to generate 6n2+1 candidate voltage vectors;(2)Simplified determination method 1 was employed,fixing the traversal count to 4 times;(3)Simplified determination method 2 was introduced,directly mapping the ideal voltage vector without traversal.[Results]Simulation and experimental results showed that the 8th order subdivision method(385 candidate vectors)reduced torque ripple by 12.87%and flux linkage ripple by 30.67%;simplified determination method 1 and simplified determination method 2 reduced computational time by 42.86%and 87.94%,respectively.[Conclusion]The proposed method achieves arbitrary expansion of candidate vectors and significant reduction of computational load,providing a reference for optimizing the performance and real-time capability of deadbeat control.关键词
