Abstract

This thesis deals with controller design for discrete-time linear systems using control Lyapunov function (CLF) technique. Since a single control Lyapunov function is usually designed for one specific goal only, this thesis proposes a method to combine different CLFs in order to achieve multiple goals with one controller. A smooth transient from one CLF to another is obtained by interpolation technique. The contractivity-sharing property of two CLFs is introduced and it is shown how to use this property for reducing the computational load. An algorithm is proposed to verify the contractivity-sharing property of two CLFs. Simulations and real-time experiments are performed to demonstrate the performance of the designed controllers.
