Abstract :
The authors consider the L1 optimal control problem with rational controllers for SISO (single-input, single-output) continuous-time systems. It is shown that the optimal L1 performance index with rational controllers is equal to that with irrational controllers. A sequence of rational controllers that approximates the optimal index is constructed. Convergence properties of such a sequence are studied. An example is given to illustrate the method
