Sampled-data model following control for discrete-valued input systems via improved matrix uncertainty approach

This paper considers a sampled-data model following control for continuous-time discrete-valued input systems. A synthesis condition is recast as a set of matrix inequalities via the matrix uncertainty approach, while the quantized accuracy and the switching speed of discretizing the continuous-valued signal are considered simultaneously. To reduce the conservativeness of the synthesis condition, the improved approach dividing the region of the switching intervals is also proposed.
