摘要
本文提出快速寻优设计的方法,先将高阶自控系统近似为四阶反馈系统,然后利用可估算动态性能指标的经验公式,来确定优化的初始点,最后对原高阶自控系统进行计算机优化设计。通过上机实践,证明采用这样的设计方法可以大大加速寻优收敛速度,缩短优化设计时间。本文还对双闭环控制同步发电机的七阶自控系统优化设计,进行了仿真实验,结果令人满意。
This paper presents a optimization design method that can converge much fast on the seeking optimization and shorten the optimization design time. First, the high order automatic control system is approximated to fourth order feedback system, and then use of experimental formula, which estimates its dynamic index, to determine optimization initial point, and lastly, use the computer's optimization design for original high order automatic control system. It has been proved by Computer's practice. This paper also makes optimization design and simulation for the double loop control synchronous generator's seventh order automatic control system. The results are satisfactory.
