提出了一种保证系统内稳定性和渐近H/sup ∞/干扰抑制的控制器设计方法。设计过程包括两个步骤：（1）通过代数Riccati方程方法设计H/sup无穷大/状态反馈控制器;（2）在一定的最小相位条件下，通过应用高增益观测器来渐近恢复可达到的性能。该方法利用理想观测量设计高增益观测器。结果表明，只要观测中不存在控制的直接馈通和干扰，降阶观测器就可以实现系统的渐近恢复。>
A design method of controllers which ensure internal stability and attain asymptotically H/sup infinity / disturbance attenuation is presented. The design procedure consists of two steps: (1) to design an H/sup infinity / state feedback control via an algebraic Riccati equation approach; and (2) under a certain minimum-phase condition, to recover the achievable performance asymptotically by applying high-gain observers. It makes use of the perfect observation for the design of high-gain observers. It is shown that the asymptotic recovery can be attained by using reduced-order observers, provided there is no direct feedthrough of controls and disturbances in observations. >
