基于单神经元自适应PID控制的位置扰动型电液伺服施力系统

针对位置扰动型电液伺服施力系统中多余力矩和参数变化问题，在用结构不变性原理进行补偿的基础上，采用单神经元自适应PID控制来确保系统有满意的跟踪性能。采用这种控制方法，可以较好地消除位置干扰的影响，同时克服系统的非线性及参数时变等因素的影响，提高了系统的鲁棒性和跟踪性能。仿真结果验证了上述结论。

Electro-hydraulic Torque Servo System with Position Disturbance Based on the Neural Network Adaptive PID Control

Aimed at the influence of other factors,such as the non-line property of the electro-hydraulic torque servo system with position disturbance and the parameters variation,based on the compensation with unchanged structure principle,the neural network adaptive PID control was presented to eliminate the disturbance torque and ensures the system of satisfactory tracking property.By means of this control method,the disturbance torque is decreased and the robustness and tracking property of systems are improved greatly.
