针对火电厂主蒸汽温度系统大惯性、大迟延、非线性的特点，根据串级控制系统参数寻优的相关规则，以改进型单纯形法为基础，并结合Matlab软件对过热蒸汽参数进行优化。传统的Ziegler-Nichols参数整定法在PID控制设计中已经得到了普遍的应用，但是寻优过程过于繁琐，存在一定的局限性。将新的整定方法应用到超临界机组主汽温调节器参数优化设计中，与传统控制方法相比，该方法有效减小了系统的超调量，提高了系统的响应速度，并起到良好的控制效果。仿真结果表明，在控制算法不断发展的今天，单纯形法依然有着一定的优势与发展空间，有待继续研究。

The main steam temperature systems of the fossil power units feature large inertia, long time delay and non-linearity, for this situation, and in accordance with relevant rules of parameter optimization for cascade control systems, with improved simplex method as the basis;the parameter optimization of super heated steam system is conducted using Matlab software. Traditional Ziegler-Nichols parameter tuning method has been widely applied in PID control design, but the optimization process is too cumbersome and certain limitation exists. Comparing with the traditional control method, using new tuning method in the main steam temperature regulator, the overshoot of the system is reduced, the response speed of the system is enhanced, and excellent control effect is obtained. The result of simulation indicates that although the control algorithms is evolving today, the simplex method still possesses certain superiority and development space;continue to study is awaited.
