Microcontroller based applied digital control ( 2006)

This book is about the theory and practice of microcontroller based automatic control systems engineering. A previous knowledge of microcontroller hardware or software is not required,but the reader will find it useful to have some knowledge of a computer programming language. Chapter 1 of the book presents a brief introduction to the control systems and the elements of computer based control systems. Some previous knowledge of the theory of continuous-time control systems is helpful in understanding this material. Chapter 2 is about system modelling. Modelling a dynamic system is the starting point in control engineering. Models of various mechanical, electrical, and fluid systems are introduced in this chapter. hapter 3 is devoted to the popular PIC microcontroller family which is described and used
in this book. The PIC family is one of the most widely used microcontrollers in commercial and industrial applications. The chapter describes the features of this family, and basic application
notes are also given.
The book is based on the C programming language known as PICC Lite. This is distributed free by Hi-Tech Software and is used to program the PIC family of microcontrollers. Chapter 4 gives a brief introduction to the features of this language. The microcontroller project development cycle is described in some detail in Chapter 5. The knowledge of the microcontroller development cycle is important as the developed controller algorithm has to be implemented on the target microcontroller. Chapters 6 and 7 are devoted to the analysis of discrete-time systems. The terms discretetime system, sampled-data system and digital control system are all used interchangeably in the book and refer to the same topic. The sampling process, z-transforms, and the time response of discrete-time systems are explained in detail in these two chapters.
