| 摘 要： | 将非线性预测控制应用于ＳＲＭ传动系统，建立了非线性参数预测模型，并在此基础上优化、校正，设计了ＳＲＭ的非线性速度预测控制器。该控制器具有实时预测、实时优化、实时校正的特点，很好地补偿了ＳＲＭ的非线性特性。与传统ＰＩ控制器相比，非线性模型预测控制器能提供更好的动态、静态特性，转矩脉动大为减小。（仿真结果表明，该控制策略不但正确、有效，而且使ＳＲＭ传动系统性能得到改善。

| Abstract: | A nonlinear continuous predictive control method is applied to SRM drive, and a predictive model with nonlinear parameters is constructed for the design of a nonlinear speed predictive controller, which is based on the optimization and feedback on line real time and compensates the nonlinear characteristic in the system. In comparison with PI controller, the nonlinear model predictive controller can provides better dynamic and static performance, motor's torque ripple is significantly reduced. Simulation results show that the proposed control scheme is not only effective, but also improves performance of SRM drive. |
