In this paper, an event based implementation of sliding mode control with quantized state measurements only is analysed. In many practical applications , the state information are available up to some finite precision. This indeed induces some quantization error into the system. However, in this work we consider the sampled state information are quantized measurements and the systems is subjected to both sampling (measurement) induced error and quantization error. The sample measurements are used in event condition. We also ensure that, there is no accumulation of triggering instants occur. Numerical simulations are provided to show effective of the above analysis. © 2015 IEEE.
