【Abstract】 A class of plants with output multiplicative unce rtainty is considered in two-degree-of-freedom control structure.A sufficient condition that two controllers satisfy is derived in order that the closed syst em has both robust stability and robust performance.As a result, the two-degree -of-freedom H ∞ control problem can be converted to the standard H ∞ control problem and a method for solving it is given.更多还原
