摘要
为了提高鲁棒性,在文献[6]所导出的自适应律中加进相关死区和“约束项”,本文证明了只要适当设计相关死区和约束项,尽管存在有界扰动和建模误差或(和)一定的时变和非线性特性,自适性控制系统仍然是全局稳定的,并用这种鲁棒自适应控制技术建立了水轮发电机组的自适应转速控制系统,经过电站实验,证明了这种自适应控制系统的有效性。
In order to achieve the robustness,a relative dead zone and a bounding term are added in the adaptive law presented in reference[6]. It is shown that,with a suitablely designed relative dead zone and bounding term,the adaptive control system is globally stable,even in the presence of bounded disturbances and unmodeled dynamics or/and certain time-variant and nonlinear property. An adaptive speed control system is presented with above robust adaptive control technique. The efficiency of the adaptive speed control system has been shown by some experiments in a water power plant.
