PID control of ball and beam system – A real time experimentation

481-484Ball and beam system is a nonlinear, open loop unstable and second order integrating process which is widely used as a test bed for evaluating various control strategies. The stabilization of ball and beam system by Proportional, Integral and Derivative (PID) controller is investigated. Simple internal model control (SIMC) based PID controller and H infinity controller are deliberately employed for stabilizing the ball at a desired position on the beam. The simulation and experimental results which demonstrate the dynamic behaviour of ball and beam system, reveals the effectiveness of controller in industries for any second order integrating processes

Design and Implementation of Iterative Learning Control for an Electro-Hydraulic Servo System

579-588In order to produce an accurate movement of double-acting hydraulic cylinder of the Electro-Hydraulic Servo System (EHSS), an Iterative Learning Controller (ILC) approach is implemented in this work. Nonlinearity and imprecision occurs in the hydraulic systems because of friction. Traditional controllers are incapable of providing effective control performance throughout the entire operating range and insufficient to handle repetitive task. To manage the repetitive task, a memorybased learning control analysis is suitable. This research focuses to construct the ILC for governing the servo spool valve, which is responsible for the hydraulic cylinder displacement. The proposed ILC consists of learning filter, learning gain and robustness filter. Proportional, Integral and Derivative (PID) controller is devised to validate the outcome of ILC. Controllers are constructed based on the system modelling. The effectiveness of the suggested controller is shown through simulation and experimental findings. ILC provides an average of 50% minimal overshoot and settles 7 sec before the PID controller is designed. Due to model uncertainty, PID controller results 0.2 sec better rise time than ILC. In ILC's architecture objective function is designed to achieve minimal overshoot and quick settling of hydraulic cylinder. So, no consideration is given to the error indices. These findings will help hydraulic stamping application, which requires the accurate displacement of piston to avoid damage of work piece. These results show that the proposed controller achieves desired outcome displacement of hydraulic cylinder
