摘要
根据C.F.KURTH和G.S.MOSCHYTZ的采用z域四口等效电路对开关电容网络进行双口分析的理论,以现场可编程模拟阵列FPAA实现的PID控制器为例,建立用于频域仿真的SPICE模型,从而方便地用SPICE软件对PID校正后的整个控制系统的稳定性进行仿真分析。
Base on the C.F. Kurth and G.S. Moschytz's theory of two-port analysis of switched capacitor networks using four-port equivalent circuits in the z-domain. The SPICE model of the PID controller based on FPAA is built, which is used for simulation in the frequency-domain. So the stability analysis of the whole control system adding the PID can easily be done.
