Abstract :
The design of an optimal finite-wordlength LQG compensator which is implemented in fixed-point arithmetic is considered. A quadratic performance index is to be minimized subject to a unity l2 -scaling constraint on the compensator states, and the desired fractional state wordlength is a parameter of the design. The compensator is optimized with respect to its structure as part of the design procedure
