This paper presents a method to design explicit control Lyapunov functions for affine and homogeneous systems that satisfy the so-called “Jurdjevic-Quinn conditions”. For these systems a positive definite function is known that can only be made non increasing by feedback. We describe how a control Lyapunov function can be obtained a deformation of this “weak” Lyapunov function. Some examples are presented, and the linear quadratic situation is treated as an illustration. ...
