EE 42****: DESIGNING WITH MICRO SYSTEMS
PRE- REQUISITE: Basic knowledge of microprocessors and microcontrollers is required COURSE OBJECTIVES:
Micro-controllers have one of the most used methods of incorporating intelligence into automated devices. Their general purpose nature, speed and size have made them one of the most common components in Electrical Engineering. It is therefore necessary to develop a good understanding of operations and how they can be used as building blocks for automated systems and control applications. The student will be able to incorporate these concepts into their electronic designs for other courses where control can be achieved via a microprocessor/controller implementation. Although assembly language programming is a large component of the course, this course is extremely hardware-oriented. Students will comprehend the basic requirements and layout for building a microcomputer and applying those concepts to achieve a dedicated “embedded” controller as a component of a larger system. Real world control problems will be solved as applications of embedded controllers, as outlined in the project design.
COURSE OUTCOMES:
After completing the subject student will be able to:
EE42***(T).1: Develop understanding of various architecture of microprocessors and microcontrollers.
EE42***(T).2: Ability to develop optimal programs in assembly level language and higher level language for any embedded real life system applications.
EE42***(T).3: Ability to design real life projects for industrial, domestic and Power system applications.
EE42***(T).4: Debug and analyze the performance of the hardware and software design.

EE 42****: SAMPLED DATA & NON LINEAR CONTROL SYSTEM
PRE- REQUISITE: Control systems and Digital signal Processing COURSE OBJECTIVES:
Almost all systems have signals in analogue form. The systems such as a chemical process, hydro- propeller, air craft wings etcetera require precision handling. Thus either these system undergo purely analogue treatment or get subjected to sampled signals. The sampling process enables the signals to get processed to digitization. The feedback control law is devised by using this digitized signal. The digitized control signal either is directly used or may be converted to analogue form as the case arises, to drive the actual plant. Thus sampled data control system gives a clear understanding how digital control systems work.
Similarly in many situations the control signal driving the system is not indefinite in magnitude, because of the limitations in actuating devices. Also, signal transmission via non-ideal gears face so called backlash or hysteresis. Thus limitations and backlash are some of many kinds of nonlinearities present inherently in all the practical systems. Hence, the analysis of nonlinear control system takes up the part of this course.
COURSE OUTCOMES:
EE42***(T).1: Understanding the concept of sampling, that leads to the mathematical treatment. Also correlate between frequency domain and z- domain characteristics.
EE42***(T).2: Exposure to the effect of sampling upon the system resulting into so called pulse transfer function. Holding sampled signals that modify the pulse transfer function.
Conceptual understanding of fictitious and actual time responses.
EE42***(T).3: Analysis of pure digital control systems and obtaining digital output response. Closed loop stability analyses and mathematical understanding of error dynamics.
EE42***(T).4: Types of nonlinearities encountered in practice. State space and phase plane techniques of analyses of nonlinear systems. ON-OFF control and its mathematical treatment.
EE42***(T).5: Stability analyses in detail to grasp the true understanding of devised control laws for both sampled and nonlinear control systems..
