Abstract:
The authors mainly studied the observability of autonomous discrete control systems and nonautonomous discrete control systems using Brouwer’s fixed point theorem. We found that if the nonlinear part f is continuous in x and bounded and moreover r(M)=n, then the autonomous discrete control system is locally observable. If there exists positive integer N, such that matrix M has column full rank, and f(i,x(i)) is continuous in x for each i∈[h,h+N-2], i is a positive integer and bounded, then the nonautonomous discrete control system is locally observable in step h.
Key words: nonlinear discrete control system, observability, Brouwer’s fixed point theorem
