摘要
从矛盾指标问题的求解出发，提出了满意解的折衷优化原理。通过分析指标间的速度型矛盾度和速度型接近度来确定各指标的折衷权值，并将求得的折衷权值代入总体满意度函数进行满意优化设计。以二阶欠阻尼控制系统的设计为例，优化出系统的最佳阻尼比。
The essence of design in control system is a problem of solving contradictory performance criteria (CPC) .In this paper, a new design principle, satisfactory optimal principle (SOP),is proposed in accordance with CPC. The weights of all-around performance criteria satisfactory function are obtained by analyzing approximative extent base on speed feature of CPC. An example of finding optimal damped ratio in second order underdamped control system is given.
