A dynamic programming based procedure for the synthesis of near-optimal controllers for sampled data systems is proposed. The main features of the proposed procedure are the approximation of nonlinear systems by piecewise affine systems, the synthesis of control strategy in the form of a piecewise constant map, and handling of state constraints and exogenous inputs. In order to increase accurac...

The robust stability condition for sampled-data control systems with a sector nonlinearity was presented in our previous paper. Although it is applicable only to the sampled-data control system of a certain class, a usual discrete-time control system can belong to this type of class. This paper analyzes the amplitude dependent behavior of nonlinear sampled-data (i.e., discrete-time) control sys...
