抓住给定值阶跃响应过渡过程性能指标中存在的主要矛盾培训,构造了一种以三个分立的过渡过程曲线特征参数为组成部分的性能指标函数。该性能指标函数在保持主要性能指标平衡性的基础上,加入了最大动态偏差限制、负向波动参数和过渡过程时间参考值,从而在保证稳定性的同时体现了控制要求和实际对象的动态特性,因而具有良好的适应性和针对性。仿真试验结果表明,使用该性能指标函数优化得到的系统,具有给定动态偏差范围内快速的阶跃给定值跟随性能,具有良好的抗扰动性能和鲁棒性。
In order to grasp the main contradiction training in the performance index of the transient response of a given value, a performance index function with three discrete transition curve parameters as the components is constructed. Based on the balance of the main performance indexes, this performance index function incorporates the maximum dynamic deviation limit, the negative fluctuation parameter and the reference value of the transition process time, so as to guarantee the stability and reflect the control requirements and the dynamic characteristics of the actual object , So has good adaptability and pertinence. The simulation results show that the system optimized by using the performance index function has a fast follow-up performance with step reference given within a given dynamic range, and has good anti-disturbance performance and robustness.
