ELEN433: Systems and Control Laboratory

Location: PBS Pinchback Engineering Building, Suite 438

Purpose of the Lab:

The purpose of this laboratory is to reinforce fundamental concepts on Systems and Controls discipline through hands-on laboratory experiments. It is designed to be in conjunction with the lecture courses of Continuous Control Systems Analysis (ELEN 431) and Discrete Control Systems Analysis (ELEN 432). The lab assignments cover the fundamental aspects of both Continuous and Discrete Control Systems.

Equipment/Apparatus:

The Systems and Control Laboratory contains four complete sets of Analogue and Digital Servo Systems (33-001-USB) and six complete sets of Modular Instructional Servo Systems (MS150) from Feedback Inc. Both analog control and computerized digital control experiments can be implemented at this laboratory. The Servo Trainer 330 system has been designed to investigate fundamental principles of servo control, both continuous and discrete. The continuous control principles are presented in progression from operational amplifier characteristics, through position and velocity feedback, to the 3-term PID control and closed loop frequency response investigation. The discrete control principles include A/D and D/A conversion, absolute and incremental encoding as well as position and speed control. In addition, the MS150 Modular Servo System is a unique medium for learning the theory and practice of automatic control systems. The system comprises a base-plate and 20 units which are supplied as the complete control system, including the dc system, ac system and the conversion unit from one system to another.
