Abstract
This paper deals with an integrated design of structural and control systems with a fault tolerant property. We obtain the optimal structural and control design parameters simultaneously by using a polynomial matrix approach. The polynomial matrix approach enables us to deal with a change of the closed-loop pole location in a case of a sensor and/or an actuator failure without substantial conservatism unlike traditional robust control approach based on Small gain paradigm. The condition where the closed-loop poles location remain in a specific region of the complex plane even in the sensor and/or the actuator fault is given as a simultaneous LMIs on the structural and the control design parameters. Those parameters are optimized simultaneously to optimize the property, e.g., energy for control, etc. while satisfying the fault tolerant property. With a design example we show the effectiveness of the present integrated design method.
