A control system is an interconnection of components making a system arrangement that will provide a desired system response. The basis for analysis of a system is the foundation provided by linear system, which assumes a cause effect relationship for the components of a system. Since control systems are provided with sensors and actuators it is also possible to obtain models of system dynamics from experiments on the process. The models are restricted to input/output models since only these signals are accessible to experiments, but modeling from experiments can also be combined with modeling from physics through the use of feedback and interconnection.


This book “Engineering Systems Modelling and Control” provides a unified introduction to the basic modelling of engineering systems as well as the development and advances in modelling and simulation, contributing to the understanding of different complex engineering systems. In this text, we describe a general process for designing a control system. To understand the purpose of a control system, it is useful to examine examples of control systems through the course of history. A model is a precise representation of a system’s dynamics used to answer questions via analysis and simulation. The model we choose depends on the questions that we wish to answer, and so there may be multiple models for a single physical system, with different levels of fidelity depending on the phenomena of interest. This text presents insight into the concept of modeling, and provides some basic concepts on two specific methods that are commonly used in feedback and control systems. Roughly speaking, a dynamical system is one in which the effects of actions do not occur immediately. For example, the velocity of a car does not change immediately when the gas pedal is pushed nor does the temperature in a room rise instantaneously when an air conditioner is switched on. Similarly, a headache does not vanish right after an aspirin is taken, requiring time to take effect. In business systems, increased funding for a development project does not increase revenues in the short term, although it may do so in the long term (if it was a good deal). All of these are examples of dynamical systems, in which the behavior of the system evolves with time. This text is primarily intended for those just beginning their engineering careers, or for practicing engineers who are changing fields or who need a brush-up as well as for senior technicians who want to press ahead into more advanced engineering design work can also benefit from it.
