ABSTRACT
The early control engineers had accounted for the essential features of a dynamical system before devising a control system to keep the dynamic system on track. With the advent of digital computers, the theoretical basis and the range of applications of control systems has witnessed dramatic improvements in the past few decades. There are two sets of variables—the controlled variables and the manipulated variables. The purpose of a control system is to keep the controlled variables close to the desired values. The manipulated variable is the one the authors change to keep the controlled variable close to a desired value. Therefore, the manipulated variable and the controlled variable should have some relationship. A disturbance is such a signal coming from either outside or inside the system that influences the variables of the control system. To develop a model-based controller, the authors study how they can design a simple model-based controller with the dynamic equations derived.
