Abstract
To solve the inadequacy of permanent magnet synchronous motor d,q axis current linearization decoupling with traditional PI control algorithm,the current predictive control based on input/output feedback linearization decoupling algorithm was proposed. By using the feedback linearization theory ,Lie differential operation was performed on the output variables of the nonlinear system. By nonlinear state feedback decoupling control and coordinate transformation,original affine nonlinear system was decomposed into two linearization subsystems of speed and excitation current. Reasonable linear regulator was designed to implement subsystem output′s trace of given input, then the high-performance control of speed and current was realized. Experimental results verify the effectiveness and practicability of the new current prediction control algorithm.关键词
