Nonlinear Robust Controller Design for Permanent Magnet Linear Servo Motor System
【摘要】 针对永磁直线电机伺服系统数学模型非线性的特点设计L2鲁棒控制器,将跟踪和扰动抑制问题归结为L2控制问题.通过构造适当的存储函数得到描述系统L2控制器的定理;证明定理给出的控制器能满足干扰抑制和系统的渐近稳定.仿真结果表明,用该方法设计的系统能很好地抑制扰动和跟踪给定,满足对高性能永磁直线伺服系统控制的要求.
【Abstract】 L2 robust controllers are designed for permanent magnet linear servo motor nonlinear model.The tracking and disturbance attenuation problem is trans formed into an L2 control problem.A theorem describing L2 robust controllers is given by a properly defined storage function.Furthermore,the L2 robust control laws are shown to achieve the disturbance attenuation and asymptotic stability.Simulation results show the effectiveness of the proposed method.
