摘要
研究了混合H2/H∞控制问题,在保证系统一个输出满足给定H∞干扰衰减约束下,使另一个输出的H2性能指标最小,在此基础上,推出了一个控制器存在的约束条件,给出了控制器的求解方法,并以数值实例证明了所提算法是可行的.
The paper mainly studies the mixed H2 /H∞control problem.A minimum for H2 performance index of one output of the system can be obtain ed under the condition of a given H∞ disturbance attenuation constrain t on the other output is satisfied.Based on this,a constraint condition on th e existence of controller is deduced and a kind of solution approach on controller is obtained.Numerical example a lso demonstrates that the algorithm pre-sented in this paper is feasible.
