Hi,
I am a novice in control systems, and struggling on where to start to tune a Gas Engine governor for simulation i am carrying out - i have a basic knowledge of PID control but not much specifics.
I have a generic governor model, available for a gas engine in the software package i am using (see below). The simulations i am carrying out show that the system is becoming increasing unstable and not settling, so i know i need to tune the values of T to manage the integral and derivative components. What i am struggling with is knowing which ones to tune and which to leave alone.
I know that the gain K has to be set low at around 2, as the engine has a very slow response to a load step, but then i assume i have to adjust T1 as the Integral function and T2 and T3 are the derivative to control its settling onto the new value? I am not really sure what T4 controls and i assume that the functions after the limiter are for the engine and to be left alone. Am i on the right lines - any help much appreciated?!
