PID control
PID control applications - Temperature and position control

The system is closed-loop controlled [S 7 090] ref [10] (figure 1 ). The aim is to determine a PID controller that provides good control performance. The system is to be identified from closed-loop tests only. We restrict ourselves here to systems that can be stabilized by a proportional corrector. If the system does not satisfy this constraint, it will certainly require a more complex control than the PID controller, and we won't entrust this task to a technician.

The PID corrector elaborates the control u from the deviation, ε = y _d...
