摘要
针对低噪声功率放大器(LNB)温度控制系统的非线性,时变性,大滞后等特点,采用PID-NN控制策略来实现温度控制,并且给出了单片机控制实现的具体方案。实验结果表明,该电路简单可靠,运行稳定;对于低噪声功率放大器的温度控制,与普通PID控制器相比,PID-NN参数自适应算法具有较好的控制性能和较强的鲁棒性。
A temperature controller structure based on PID-NN for_J_ow Noise Block (LNB) module is studied in this paper. And its implementation with MCU is also given. The controller is also suitable for various high order plants. The computer simulation and the experimental results demonstrate that the control performance of the controller is superior to that of the conventional controller. Furthermore, this kind of controller is stronger robust than eonventional controller when applied to the nonlinear, uncertain plant.
