Objectives
Be able to...
Choose a type of controller suited to a set of specifications,
Simplify models and determine their validity range,
Calculate the parameters of a P, PI, phase advance, or PID controller using different methods,
Choose the method based on the context and specifications,
Description
Scenario: support application
Advantages of closed-loop control: open-loop, closed-loop, proportional correction, stability, accuracy, speed = a cruel dilemma!, calculation of proportional controller/specifications
Integral controllers: dominant pole compensation method, symmetrical optimum method, 1/10 method, implementation
Derivative controllers: calculation of parameters by imposing bandwidth, by the pole compensation method, implementation
PID controllers: calculation by pole compensation, by PI combination – Phase advance
Experimental methods for adjusting PI and PID controllers: Expert adjustment, Broïda method, Ziegler Nichols method, and relay method
Control architectures: PI and more... More state variables to control; a little anticipation
Conclusion: comparisons, summary and outlook
Pre-requisites
Basic calculations with Laplace transforms: signal transforms, inverse transforms, final value theorems, initial value theorems, delay theorems, etc.
Calculations with complex numbers.
Solving first- and second-order differential equations.
Proficiency with Bode and Nyquist diagrams.
