This is a 2nd order control system. LVDT forms part of input transducer, and stepper motor becomes the actuating element. In this trainer, simple ON-OFF control is implemented when used with Microprocessor trainer Model MPT-85. In order to allow the control action, the set point of final position of LVDT displacement forms an Input element to the controller. The controller determines how fast the desired position should reach.
In order to facilitate the above objectives, an external Microprocessor trainer Model MPT-85 will act a controller. The student learns how to write a control algorithm to meet the above objective.
