• This title is versatile and may be used for a system dynamics course, followed by a controls course, or it may be used in a controls course. It allows for easy teaching of controls using both transfer function methods and state-space methods.

• The chapters on mathematical modeling of mechanical systems, electrical systems and transport systems cover the entire range of engineering topics that employ control system methods.

• Discussion of operational amplifiers, hydraulic servomotors and pneumatic systems provide the instructor with the basics of controllers.

• Coverage of lesser-known topics includes time delay systems.

• Discussion of applications of frequency response includes vibration absorbers and electronic filters.

• Hundreds of end-of-chapter problems are included, ranging from short-answer questions to longer, more involved problems.

• Learning Objectives at the beginning of each chapter articulate the skill the student should perform/achieve upon completion of the chapter. These are specific, measurable, authentic and inclusive.

Cengage provides a range of supplements that are updated in coordination with the main title selection. For more information about these supplements, contact your Learning Consultant.
