基于统一可观测性条件的永磁同步电机参数估计优化方法

Parameter estimation of permanent magnet synchronous motors (PMSMs) is broadly researched, while the parameter observability has not been well-discussed. This article employs the local weak observability theory to obtain unified observable conditions and give a definite reference for parameter estimation. Based on the results, a novel machine parameter estimation algorithm based on convex optimiza...
