摘要
针对液压位置伺服系统的不确定性、非线性和常规PID控制器的缺点,设计了单神经元自适应PID控制器,该方法可以显著减小液压位置伺服系统中由于元件参数变化等引起的超调和振荡。利用AMESim与MATLAB软件各自的优势,分别进行了液压伺服系统建模和控制器设计。联合仿真结果表明,单神经元自适应PID控制器比常规PID控制器使系统具有更好的鲁棒性,同时使系统具有良好的环境适应性和较好的物理性能。
To the problems of uncertainty and nonlinearity in hydraulic position servo system and the shortcomings of conventional PID controller,a single neuron adaptive PID controller is designed,which can decrease the overshoot and oscillation coming from the components parameters＇ changes in the hydraulic position servo system.Based on the advantages of AMESim and MATLAB respectively,the model of the hydraulic servo system is set up and the controller is designed.The joint simulation results show that the single neuron adaptive PID controller makes the system being more robust than conventional PID controller,meanwhile,the system has better adaptability and physical properties.
