Abstract. This paper studies the exponential stabilization problem for
discrete-time switched linear systems based on a control-Lyapunov func-
tion approach. A number of versions of converse control-Lyapunov func-
tion theorems are proved and their connections to the switched LQR
problem are derived. It is shown that the system is exponentially stabiliz-
able if and only if there exists a finite integer N such that the N-horizon
value function of the switched LQR problem is a control-Lyapunov func-
tion. An efficient algorithm is also proposed which is guaranteed to yield
a control-Lyapunov function and a stabilizing strategy whenever the sys-
