摘要 四块问题的 H∞ 设计可以避免零极点对消。指出选择不同的信号组合 ,可以进一步将四块问题直接用于系统的综合。基于这一思路给出了病态对象控制和弱阻尼系统鲁棒镇定的 H∞ 综合方法 ,并结合 The pole/zero cancellation can be avoided in four block design. It is pointed out further that using proper combinations of the signals the four block problem can be used for dicect synthesis. This design idea is illustrated in H ∞ control of ill conditioned plant and robust stabilization of lightly damped systems. A design example of Benchmark problem is given.
