0 0 2 1

Prerequisite: Control Systems

Course Objectives:

• To understand the different ways of system representations such as Transfer function representation and state space representations and to assess the system dynamic response
• To assess the system performance using time domain analysis and methods for improving it
• To assess the system performance using frequency domain analysis and techniques for improving the performance
• To design various controllers and compensators to improve system performance

Course Outcomes: After completion of this lab the student is able to

• How to improve the system performance by selecting a suitable controller and/or a compensator for a specific application
• Apply various time domain and frequency domain techniques to assess the system performance
• Apply various control strategies to different applications(example: Power systems, electrical drives etc)
• Test system controllability and observability using state space representation and applications of state space representation to various systems

The following experiments are required to be conducted compulsory experiments:

1. Time response of Second order system
2. Characteristics of Synchros
3. Programmable logic controller – Study and verification of truth tables of logic gates, simple Boolean expressions, and application of speed control of motor.
4. Effect of feedback on DC servo motor
5. Transfer function of DC motor
6. Transfer function of DC generator
7. Temperature controller using PID
8. Characteristics of AC servo motor

In addition to the above eight experiments, at least any two of the experiments from the following list are required to be conducted
