Linear control systems

Linear control systems

It is a complete course in linear control systems dedicated to beginners. This field is very useful in industrial systems, especially for the control and command of a linear process. In the present course, we start by giving general information on control systems, in which the different definitions and concepts are presented. In this part, we see the Laplace transformation of differential equations and their proprieties. After this, we present the concept of transfer functions in control systems in which the notion of the open and closed loop is viewed. Next, we move to the temporal and frequency response of linear systems. In this course, the stability and precision of systems are explicated in detail in order to get an idea of linear control aims, and following that, we finish with the presentation of the manner of improving performances of systems using correctors. This course provides a general overview of linear control systems, and after learning this course, the student will get general information on the control systems field and also be able to study a physical system starting from physical modeling and differential equations until arriving at to transfer function. This list can be studied based on temporal and frequency approaches. In the end, the student tackles the corrector synthesis to improve the response performance of systems in an open and closed loop.
