The applicability of employing a parameter‐dependent control to a nuclear pressurized water reactor is investigated and is compared to that of using an ℋ ∞ control. A linear time‐invariant controller cannot maintain performance over the entire operating range. The parameter‐dependent synthesis technique produces a controller which achieves specified performance against the worst‐case time variation of a measurable parameter which enters the plant in a linear fractional manner. The plant can thus have widely varying dynamics over the operating range. The controllers designed perform well over the entire operating range. Copyright © 1999 John Wiley & Sons, Ltd.
