摘　　要：针对电厂中主汽温控制系统具有大滞后、非线性的特点,提出了一种基于Smith预估器的单神经元PSD自适应控制算法,即由Smith预估器和单神经元PSD自适应控制器组合的复合控制。仿真结果表明,这种控制方式具有较好的自适应性和鲁棒性。The main steam temperature process is regarded as a controllable process with large time delay and unmeasurable disturbances. In this paper a new single-neuron PSD self-adaptive algorithm that based on Smith predictor was proposed, that is, a compound controller was combined with Smith predictor and single -neuron PSD self- adaptive controller. Compared with conventional PID controller, the result of simulation shows that the new controller has better adaptability and robustability.
