FINITE-HORIZON STATIC OUTPUT H-INFINITY CONTROL WITH AUTOMATIC BEAM GUIDANCE APPLICATION

The problem of designing static output-feedback controllers for finite time horizon is considered. The design problem is solved in two setti ngs: one is the pure H-infinity setting where the disturbance attenuat ion problem is solved, and the other is a mixed H-2/H-infinity setting where an upper bound on the L-2 norm of the error is minimized as wel l. In the pure H-infinity setting, a single Riccati-like equation shou ld be solved, where the required projection matrix is obtained up to a free parameter. In the other setting, a two-point boundary-value prob lem has to be solved. The theory of the mixed H-2/H-infinity setting i s illustrated by a design of an automatic lateral beam guidance contro ller.
