Trainer for controller tuning. This unit permits the interaction between controller and controlled system. The objective is that the closed control loop, formed by the controller and the controlled system, to show the desired optimum response. With a simulation software the setting of controller parameters can be practised safely. Closed an open loop control, step response, stability, disturbance and control response are demonstrated. This trainer no needs real controlled systems, the controlled system is simulated on a computer (PC) by the simulation program. In this program the most important types of controlled systems can be selected . We can recorder and analyse the time response using the software. The process controller used can be easily configured from the computer (PC) across an interface using the configuration software. The controller and the computer (PC) are connected by a data acquisition card with AD and DA converters.
The trainer basically is formed by:
