Linear Parameter-Varying versus Linear Time-Invariant Control Design for a Pressurized Water Reactor

The applicability of employing a parameter-dependent control to a nuclear pressurized water reactor is investigated and is compared to that of using an H1 control. A linear time-invariant controller cannot maintain performance over the entire operating range. The parameterdependent synthesis technique produces a controller which achieves speci ed 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.
