The optimal fixed-point linear quadratic regulator

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 l/sub 2/-scaling constraint on the compensator states, and the desired fractional state wordlength is a paramet...

Summary: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 l/sub 2/-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.< >
