A scheme of almost dead beat realization technique in second order and higher order linear control system is studied. The technique involves injection of an additional pulse signal to the system to act along with its normal input of appropriate time duration with specified amplitude. In this work we also concentrated to the improvement of dead beat realization through the minor adjustment of pulse parameters i.e. the start time (ti), end time (t2) and amplitude (b). it is observed that this minor adjustment of pulse parameters in the system makes an appreciable improvement of dead beat realization in any second order and higher order linear control system We have used the technique of Multimodality using Genetic Algorithm (GA), which finds out the new value of the above three pulse parameters and then applying to the uncompensated system for better dead beat realization. Our objective is to minimize the second overshoot of the uncompensated system We have considered the expression of second overshoot of compensated system as a fitness function in GA. After conducting several iterations it is found that the dead beat realization of any linear system can be improved remarkably by choosing the small considerable domain of pulse parameters as searching space.
