摘要: The 2/spl frac12/ degrees of freedom structure considered has been used in real applications for many years but it not shown to follow from the solution an H/sup 2/ optimal control problem. A Kucera type polynomial is presented which provides a theoretical basis adopted. proposed controller advantage that low frequency tracking properties can be achieved, as single degree-of-freedom designs, no constraints then apply high behaviour, since effectively determined by two degrees-of-freedom structure. wind turbine example presented. >
