Abstract
In this work, discrete sliding mode control method in combination with non-invasive pulsatile estimator model is used to develop non-linear tracking control algorithm in the presence of bounded uncertainties and disturbances. A sate space model to estimate mean pulsatile flow based on the pulsatility index of current is constructed. The control method is introduced the reference model as part to design the algorithm. The reaching control law is proposed, and the conditions of system stability are considered. The algorithm is evaluated using dynamical closed loop system to study the robustness for the system uncertainties. Simulation results reveal the efficiency of the developed controller.
