Mechatronics: Electronic Control Systems In Mechanical and Electrical Engineering, 7th Edition by Pearson

Chapter eighteen

System models

Objectives

The objectives of this chapter are that, after studying it, the reader should be able to:

• Devise models for rotational–translational, electromechanical and hydraulic–mechanical systems.
• Linearise non-linear relationships in order to generate linear models.

18.1 Engineering systems

In Chapter 17 the basic building blocks of translational mechanical, rotational mechanical, electrical, fluid and thermal systems were separately considered. However, many systems encountered in engineering involve aspects of more than one of these disciplines. For example, an electric motor involves both electrical and mechanical elements. This chapter looks at how single discipline building blocks can be combined to ...
