Guaranteed cost control for sampled-data systems

Guaranteed cost control (GCC) via output feedback for sampled data systems is considered. In terms of a Riccati inequality with jumps, the GCC problem for a sampled data system is defined. For uncertain sampled data systems, the GCC controller can stabilize the closed loop system and guarantee an adequate level of performance. Motivated by some results on H_∞ control for sampled data systems, we transform the GCC problem to a H_∞ control for a linear system with jumps. Simulation results show the GCC is efficient and practicable
