Abstract :
The stability properties of the pseudoinverse method in reconfigurable control are analyzed. To guarantee stability, the reconfigurable control problem is formulated as a constrained minimization problem. A modified pseudoinverse method is proposed which guarantees the stability of the reconfigured system for the class of single-input multioutput systems; a closed-form solution is derived in this case. For general multi-input multioutput systems, the problem is formulated as a minimization problem subject to simple bounds, for which many numerical methods are available in the literature of optimization theory
