【摘要】 针对液压自动位置控制(HAPC)系统的不确定性等问题,首先建立了IAPC系统的被控对象模型,然后设计了一个不依赖于对象模型的自抗扰控制器,并采用粒子群优化算法对控制器参数进行优化,最终利用优化后的ADRC控制器对HAPC系统进行了仿真控制研究.结果表明:基于粒子群优化算法的自抗扰控制器在IAPC系统中具有较好的跟踪性、抗干扰性和鲁棒性.更多还原

【Abstract】 In view of Hydraulic Automatic Position Control (HAPC) with uncertainty and nonlinearity, the model of HAPC system is established. Then. a controller independent on the model is designed. And particle swarm optimization (PSO) is presented for parameters optimization of the ADRC controller. Finally. ADRC optimized by PSO is selected as the controller for BAPC system and the simulation results show that it has better performance in tracking. anti-interference and robustness compared with other three algorithms.更多还原
