基于离散时间趋近率控制与内模控制的永磁同步电动机传动系统
PM SYNCHRONOUS MOTOR DRIVES BASED ON DISCRETE-TIME REACHING LAW AND INTERNAL-MODEL CONTROLS
摘要
Abstract
A robust control technique for permanent magnet synchronous motor (PMSM) is proposed to reduce the sensitivity of drive to the accuracy of machine model, and to simplify the design procedure of controllers. First, highly robust internal model control (IMC) is used in the current control, and the synchronous-frame PI-type IMC controllers are expressed directly in machine parameters and desired closed-loop bandwidth, which avoids the adjustment of two PI-parameters;moreover the IMC structure improves the characteristic of current loop. Then, the speed controller of PMSM drive is proposed by using the principle of reaching law control (RLC),and the design equations are derived in the discrete time since the discrete time analysis and design are more appropriate for the digital control applications. The stability of the RLC-based controller in the speed loop is analyzed. Simulation results verify the proposed drive.关键词
