Abstract :
A convex optimization controller design method is presented which minimizes the closed-loop H2 norm, subject to constraints on the magnitude of closed-loop transfer functions and transient responses due to fixed inputs. This method is applied to the roll axis of the EOS-AM1 spacecraft attitude control system, with a set of performance and robustness specifications. This example serves as a good benchmark problem, because it has been used for previous model-based control studies. A controller is designed using constrained H2 which successfully meets all of the design specifications of a previous study
