摘要
针对永磁同步电机调速系统中传统滑模控制(SMC)存在超调较大以及响应速度慢的问题,提出一种基于新型分数阶趋近律的非奇异终端滑模速度控制器。控制器通过采用非奇异终端积分滑模面,并结合分数阶理论引入新型分数阶趋近律,避免终端滑模的奇异性问题,提升系统的动态响应速度和调速稳定性。同时,根据Lyapunov定理对其稳定性分析。最后,通过仿真结果表明,与传统滑模控制(SMC)相比,采用基于新型分数阶趋近律的非奇异终端滑模控制(NSMC)能够提升系统的响应速度,减小超调,增强系统的调速稳定性。
In order to solve the problem of large overshoot and slow response speed of traditional Sliding mode control(SMC)in permanent magnet synchronous motor(PMSM)speed control system,a nonsingular terminal sliding mode speed controller based on a new fractional order reaching law is proposed.This controller adopts a non singular terminal integral sliding mode surface and combines fractional order theory to introduce a new fractional order reaching law,avoiding the singularity problem of terminal sliding mode and improving the dynamic response speed and speed stability of the system.Meanwhile,its stability is analyzed based on Lyapunov's theorem.Finally,the simulation results show that compared with the traditional Sliding mode control(SMC),the non singular terminal Sliding mode control(NSMC)based on the new fractional order approach law can improve the response speed of the system,reduce overshoot,and enhance the speed regulation stability of the system.
