Lab 11: PI Feedback Control. This week’s lab focuses on the use of PI feedback control to produce a constant current source using. a noisy voltage source. The lab is the simulation version of problem #2 on the homework.
The PI controller adds a pole and zero to the system. Since the load is at least of a first order, more complex (and possibly oscillating) dynamics will be seen by the system. The sum of the two controller paths is as follows: Hence, the pole is located at origin (s = 0 rad/s) and the zero is located at -Ki/Kp rad/s.
Basic block of a PI controller. A PI controller(proportional-integral controller) is a special case of the PID controller in which the derivative (D) of the error is not used. The controller output is given by. KPΔ+KI∫Δdt{\displaystyle K_{P}\Delta +K_{I}\int \Delta \,dt}
To answer this question, let’s drop the PI controller into the heart of a current mode controller which is controlling a motor, as shown below. We will use a first-order approximation of the motor winding to be a simple series circuit containing a resistor, an inductor, and a back-EMF voltage source.
In the proportional-integral controller, the control action of both proportional, as well as the integral controller, is utilized. This combination of two different controllers produces a more efficient controller which eliminates the disadvantages associated with each one of them.
