Stabilization of internal dynamics using time multiplexing of inversion and sliding mode control for high boost converter

Time multiplexing of inversion and sliding mode control, a non-linear control strategy is applied to analyse the performance of the high boost converter and the results are verified experimentally. As it is a non-linear control technique there is no need of linearizing at a particular operating point. This control tech nique is applicable for getting the output from zero to the maximum voltage range of the high boost converter. Inversion control technique makes the out put of the system one hundred per cent insensitive to any kind of disturbance and the control input tracks the output to the desired trajectory. As this kind of tracking demands high input currents, a new approach to track the output volt age trajectory and simultaneously keep the high input currents within limits is discussed. The new design technique multiplexes the inversion and sliding mode control to generate desired output tracking performance and to stabilize the unstable internal dynamics(higher input current). The control method is implemented, analysed and verified on MATLAB. Internal dynamics are sta bilized using time division between the two control techniques i.e. Inversion and sliding mode. By defining appropriate exponential tracking trajectory and error surface, it is shown that even non-minimum, non-linear systems can be stabilized by time multiplexing the inversion and sliding mode control. This presentation also includes the comparison between the traditional linear model control techniques like PID controller and the non-linear control techniques.
