| 摘 要： | 本文提出一种改进的水轮机微机调速器PID控制算法,并建立了采用原始PID算法和改进PID算法的水轮机调节系统的离散数学模型,给出了调节系统的稳定域边界控制方程,并对两种PID算法的调节系统稳定域进行了分析比较。结果表明,改进PID算法消除了延时环节引起的误差,比原始PID算法的精度高,运算速度快;采用改进PID算法较采用原始PID算法的调节系统稳定域大。

| Abstract: | A kind of improved control algorithm for microprocessor based on PID governor of hydro turbine is presented in this paper. The mathematical models of the hydro turbine governing systems are established by preliminary PID algorithm and improved PID algorithm respectively. From analysis of the boundary control equations of the system and the stability domain, it proves that the improved PID algorithm eliminates the errors caused by the delaying unit with higher calculation accuracy and faster calculation speed, and the stability domain of the improved PID algorithm is wider than that of the preliminary PID algorithm. |
