— In this paper, we consider the problem of finding a time-varying controller which can stabilize a decentralized discrete-time system. In continuous-time, it was already known that time-varying decentralized controllers can achieve stabilization in cases where time-invariant decentralized controllers cannnot. This paper works out the details for the discrete-time case.
