摘要
针对非均匀气隙永磁同步电机(PMSM)混沌系统,提出一种改进的主动有限时间同步控制器.该控制器首先利用主动控制来实现动态误差系统非线性项和线性项的近似解耦,再通过有限时间稳定控制来实现驱动系统和相应系统的有限时间同步.通过仿真实验,验证了该控制器比传统的控制器具有更强的鲁棒性和快速响应能力.
A novel active finite-time synchronous controller is proposed for the chaotic system of permanent magnet synchronous motor （PMSM） with nonsmooth air-gap.In this controller,the active control is used to decouple the linear terms and nonlinear terms of the dynamic error system.Then,we use finite-time stability theory to design the controller which can achieve finite-time chaos synchronization of the drive system and response system.Simulation results show that the presented control scheme is more effective than traditional ones in robustness and rapid response capability.
