摘要 所有实际的运动机构中都包含一定的非线性,对其进行精确的建模和控制是运动控制中具有挑战性的难题。文中提出了基于粒子群优化算法的RLS-PSO系统辨识建模方法,所得伺服转台模型具有良好拟合效果;对该模型提出改进的两步法,应用基于预测函数控制(Predictive functional control,PFC)的全局优化预测控制;伺服转台的仿真运行结果表明跟踪效果良好。 There are nonlinearities almost in all of the kinematic mechanisms. The accurate modeling and precise control are both challenging problems in the field of kinematic control. An approach to RLS-PSO parameter identification based on particle swarm optimization is approved, which gets a great model of servo turntable. The global optimization predictive controller based on predictive functional control （PFC） is applied to the servo turntable through modified two-step method. And the simulation results show the effectiveness of modeling method and control algorithm of the servo system.
