Objectives
Be able to…
• Choose a type of controller suitable for a specification,
• Simplify models and determine their domain of validity,
• Calculate the parameters of a P, PI, Phase-Advance, PID controller using different methods,
• Choose the method and structure of the controller based on the context and specifications,
Description
Interest of the closed loop: open loop, closed loop, proportional correction, stability, accuracy, speed = tough dilemma!, calculation of the proportional controller / specifications
Integral-type controllers: dominant pole compensation method, symmetrical optimum method, 1/10 method, implementation
Derivative-type controllers: calculation of parameters by imposing the bandwidth, by the pole compensation method, implementation.
PID-type controllers: calculation by pole compensation, by PI combination – Phase lead
Experimental methods for tuning PI, PID controllers: Expert tuning, Broïda method, Ziegler-Nichols method, and relay method
Control architectures: PI and beyond…, more state variables to control, a bit of anticipation
Context: supporting application
Pre-requisites
- Continuous Linear System, basic calculations with Laplace transform
- Calculations with complex numbers, solving first- and second-order differential equations
