Abstract

A method of proportional-integral-derivative, PID, control of a controlled system is provided. The method comprises: determining an error between a setpoint of the controlled system and a state variable of the controlled system; determining a control signal based on a sum of a proportional term, an integral term, and a derivative term, each of the terms being a function of the error and being weighted by a respective gain; and applying the control signal to the controlled system. At least one of a gain of the integral term or a gain of the derivative term is based on the setpoint and the state variable.
