1. A controller for controlling a power stage of a power converter according to a control law, the control law implementing a specific type of compensator and being pre-designed to generate an optimal response of a default power converter for a default parameter value of a component of the power stage; the specific type of compensator being any of P, I, D, PI, ID or PID; the controller being further configured to alter the control law for an actual parameter value of the component of the power stage such that the optimal response is retained by
adjusting a proportional gain according to a ratio of the actual parameter value and the default parameter value by multiplying a default proportional gain corresponding to the default parameter value by the ratio if the compensator is any of P, PI or PID type;
adjusting a integral gain according to a ratio between the actual parameter value and the default parameter value by multiplying a default integral gain corresponding to the default parameter value by a square root of the ratio if the compensator is any of I, PI and PID type; and
adjusting a differential gain according to a ratio between the actual parameter value and the default parameter value by multiplying a default differential gain corresponding to the default parameter value by the ratio if the compensator is any of D, ID or PID, type.
