Analog Motor Control

zoom

This teaching set introduces students to the fundamental principles of analog and digital motor control, through a wide range of practical activities. This comprehensive teaching set includes the following items:

• DC Motor Control Module
• Command Potentiometer
• PID Controller
• 4 mm Lead Set
• Power Supply

The curriculum supplied with the teaching set covers the following topics:

• The Digital Storage Oscilloscope
• Transient and Steady-State Response
• Proportional Speed Control
• Proportional Position Control
• Second-Order Response Parameters
• Velocity and Transient Velocity
• Feedback
• Controller Characteristics
• Integral Speed Control
• Proportional Plus Integral Speed Control
• Proportional Plus Integral Plus Derivative Position Control
• Instability

The curriculum manual is fully compatible with the ClassAct computer-managed learning system. Each chapter is designed around a list of performance objectives. These objectives are used by the ClassAct management system to generate a student competency report. A student workbook is also provided, allowing students to record basic theory and practical results as they work through the curriculum manual. An instructor’s guide provides solutions to all of the questions and practical activities contained in the curriculum manual.

Typical activities for the student include:

• Describe the Main Elements of a PID Controller
• Investigate the data capture features of a digital storage oscilloscope
• Conduct simple step, ramp and frequency response tests
• Demonstrate proportional speed control
• Outline the reasons for adding velocity feedback
• Demonstrate the change in following error when transient velocity feedback replaces velocity feedback
• Discuss the effects of noise when subjected to derivative action
• Demonstrate various combinations of PID control
• Demonstrate the stabilizing effect of a proportional action on a system controlled with integral action
