Simulation of State Variable Compensator for Linearized Mechanical System

Abstract

The development of state variable approach has been made possible by mathematical modelling of a system which, alongside the output, provides information on the state of the system variables at certain fixed points along the flow of signals. The paper has presented simulation of state variable compensator for linearized mechanical system. The dynamic model of linearized mechanical system representing engine idle speed in the form of a transfer function was obtained. The transfer function was converted into state space equation and a feedback gain matrix is developed. Simulink model of the system was developed and was used for simulation in MATLAB. The step response results reveal the performance of the state variable for open loop and closed loop conditions.
