Abstract
In this chapter, the problem of \(\ell _{1}\)-induced state-feedback controller design is investigated for discrete-time positive systems based on linear Lyapunov functions. For a given positive linear system, the objective is to design a state-feedback controller such that the closed-loop system is positive, asymptotically stable and satisfies a prescribed \(\ell _{1}\)-induced performance. In detail, the exact value of \(\ell _{1}\)-induced norm is firstly computed with the use of an analytical method. A novel stability and \(\ell _{1}\)-induced performance characterization is then proposed. Based on such a characterization, necessary and sufficient conditions are derived for the existence of desired controllers. To solve the conditions, a corresponding iterative convex optimization algorithm is developed. Secondly, the controller synthesis problem for single-input multiple-output (SIMO) positive systems is investigated. Specifically speaking, an analytical method is established to obtain the optimal \(\ell _{1}\)-induced controller for the special case. Moreover, some links to the spectral radius of the closed-loop systems are provided. Finally, the effectiveness of the obtained theoretical results in this chapter are illustrated through a numerical example.
