Design of PID Controller to Reduce the Vibrations of a Vertical Washing Machine

This paper focuses on a vertical load washing machine system for vibration analysis and on its different parameters used to control the vibration intensity. Vibration control basically depends upon two major factors, i.e. vibration absorber and vibration isolator. Vibration isolation may be a common method to protect receivers (device, human, system, machine or structure) from the vibration source. For this purpose, a virtual model was designed using MATLAB and Simulink tool. After creating the model, the analysis of vibration was performed. PID controller was used to find the optimum value of controller parameters like KP, KI, KD, for obtaining a stable as well as responsive system. The observed results will help the designers in designing the machine efficiently by using the knowledge of the effects of different parameters.
