Design for Temperature Controller Using PIDNN Based on DSP

针对低噪声单元(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DSP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;对于低噪声单元的温度控制,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 using PID-NN for low noise block （LNB） module is studied in this paper. And its implementation with DSP TMSLF2407A is also gave. The experimental results demonstrates that the circuit is simple and dependable, the performance of the controller is superior to that of the conventional controller. Furthermore, this kind of controller is much more robust than conventional controller when applied to the nonlinear, uncertain plants.
