JNTUK B.Tech Digital Control Systems R13 Syllabus for Engineering it gives you detail information about Power Systems Lab syllabus.
Preamble
In recent years digital controllers have become popular due to their capability of accurately performing complex computations at high speeds and versatility in leading non linear control systems. In this context, this course focuses on
the analysis and design of digital control systems.
Learning objectives
- To understand the concepts of digital control systems and assemblevarious components associated with it. Advantages compared to the analog type.
- The theory of z–transformations and application for the mathematical analysis of digital control systems.
- To represent the discrete–time systems in state–space model and evaluation of state transition matrix.
- To examine the stability of the system using different tests.
- To study the conventional method of analyzing digital control systems in the w–plane.
- To study the design of state feedback control by “the pole placement method.”
