摘　　要：通过分析比较单纯PID控制和PID神经元网络控制对压电式气动伺服阀动态特性的影响,具体比较两种控制下压电式气动伺服阀的稳定性、快速响应性、信号跟踪能力,仿真结果表明,PID神经元网络控制比单纯PID控制对系统具有更好的稳定性、快速响应性和信号跟踪能力。First, a simple PID control and PID neural network control for dynamic characteristics of piezoelectric pneumatic servo valve are analyzed, and then stability, fast response ability, signal tracking capability of piezoelectric pneumatic servo valve under the two control way are also compared in this paper. By comparing the results, it is found that PID neural network control system has better stability, fast response and signal tracking capability than the simple PID control.
