WebEarly dynamic positioning systems were implemented using PID controllers. In order to restrain thruster trembling caused by the wave-induced motion components, notch fil-ters in cascade with low pass filters were used with the controllers. An improvement in performance was achieved by exploiting more advanced control techniques based on WebMar 11, 2024 · A PID controller controls a process through three parameters: Proportional (P), Integral (I), and Derivative (D). These parameters can be weighted, or tuned, to adjust their effect on the process. Much more practical than the typical on/off controller, PID controllers allow for much better adjustments to be made in the system.
