摘要
研究液压舵机的性能优化问题,根据控制理论建立了液压舵机伺服系统的数学模型,针对采用常规的控制方法液压舵机系统响应速度慢、抗干扰能力差等问题,对单神经元网络进行充分研究后,设计了改进的单神经元自适应PID控制器,在单位阶跃信号的作用下,运用MATLAB平台对该液压舵机系统进行仿真,并与常规PID控制、P控制进行比较。仿真结果表明,与常规PID控制、P控制相比,改进单神经元自适应PID控制有效的提高了液压舵机系统的快速性和抗干扰性,获得了良好的控制效果。
In order to analyze the property of the hydraulic actuator better, a model of hydraulic actuator serw, system was established based on control theories. Aming at the problem that the hydraulic actuator system based on conventional control method has low converging speed and low ability of anti - jamming, after fully research of single neuron network, an improved single neuron adaptive PID controller was designed. At last, the hydraulic actuator sys- tem was simulated with MATLAB/simulink under the effect of unit step signal, then it was compared with convention- al PID control and P control. The result shows that compared with PID control and P control, the improved single neuron PID control can raise the rapidity and anti - disturbance of the hydraulic actuator system effectively.
