Abstract :
Whenever we compute control using digital computer, the states measured need to be converted to digital word before processing in the computer. This conversion gives rise to quantization error in state measurement which in turn affects the applied control to the plant. This would cause the system dynamics to deviate from the behaviour predicted by any theoretical analysis which does not consider the effect of such quantization. Here an analysis has been presented taking into consideration the error due to quantization for Quasi Sliding Mode Control with state feedback.
