Output-feedback controller synthesis with sign-indefinite quadratic forms

Résumé

We provide novel sufficient conditions for the synthesis of stabilizing dynamic output-feedback controllers for input-saturated plants. Based on Linear Matrix Inequalities (LMIs), together with appropriate transformations and sector conditions, the results exposed exploit the sign-indefinite quadratic forms involving the closed-loop state and the deadzone of the control input to define piecewise smooth Lyapunov functions. The proposed solutions leverage additional degrees of freedom with respect to the classical quadratic stabilization approach to construct global or regional exponential stability certificates of the origin for the closed-loop system.
