| 摘 要： | 针对数控电液位置伺服系统的非线性、参数时变性等特点,设计一种基于CAMC和PID并行控制的方案。以PID为反馈控制来保证系统的稳定性且抑制扰动,以CAMC为前馈补偿控制器来确保系统的控制精度和响应速度。在MAT-LAB环境下对位置伺服系统进行动态仿真。仿真结果表明:基于CAMC和PID的并行控制响应速度快,稳态精度高,其控制性能远优于传统PID控制器。

| Abstract: | According to the nonlinear and time-varying parameters characters of the CNC electro-hydraulic position servo system,a CAMC and PID concurrent control method was designed.The PID controller was used as the feedback control to ensure the stability and disturbance suppression.CAMC was used as the feed-forward compensation controller to ensure the control precision and response speed.The dynamic simulation of the position servo system was made in MATLAB.The simulation results show that the CAMC and PID concurr... |
