C = pid(Kp,Ki,Kd,Tf) creates a continuous-time PID controller with proportional, integral, and derivative gains Kp, Ki, and Kd and first-order derivative filter time constant Tf:This representation is in parallel form. If all of Kp, Ki, Kd, and Tf are real, then the resulting C is...

Parallel Form Many academic textbooks discuss only the parallel form of PID controller, and don’t mention the others. The parallel form is also used in some DCSs and PLCs. This algorithm is simple to understand, but not intuitive to tune. The reason is that it has no controller gain that...
If the controller’s PID equation takes the parallel form, the technician must adjust the P, I, and D tuning parameters proportionately. If the controller’s PID equation uses Kp as a factor in all three modes, the technician need only adjust Kp to re-stabilize the loop. Ideal PID Contro...
