Piecewise continuous observer design for a class of linear systems with sampled delayed output

The paper deals with a new continuous undelayed state observer design by using only the sampled-data delayed measurements where the delay value is q fois of the sampling period. This proposed piecewise continuous observer, which is derived by using the theory of a particular hybrid systems called Piecewise Continuous Systems, has a very simple structure and can be easily implemented to the network control systems or visual servoing systems. The observer stability is also analyzed and demonstrated. To show the proposed observer performance, a comparison with a Lyapunov-Krasovskii technique and descriptor representation based observer is conducted via a numerical example. Moreover, the PCO experimental real-time application results are equally given.
