Assignment No.1: Curriculum ReviewDate: 09.03.2015

Program: B.E. Semester-IV (Electronic s and Communication Engineering)Subject: Control System Engineering (2141004)

1. Course Rationale: Its mentioned and requires no change.

2. Timing Allocation: Its mentioned and requires no change.

3. Clarity of the content: a. Topics related to P controllers, PI controllers and PID controllers should not be included because B.E. Semester IV students are unaware about basic microcontrollers like 8051. b. The topic mentioned as design of feedback control systems should be removed since students are not having any exposure about designing a circuit in lower semesters. The topic seems to be very advanced and requires much more pre-requisites which are not mentioned.

5. Assessment and Evaluation: Its satisfactory, but can be improved.

6. Resource required: Its mentioned and is good enough for undergraduate students.

7. Competence Expected of Faculty: Regular training of the faculties teaching the above mentioned subject is required.

8. Learning Outcomes: Its mentioned and is good enough for undergraduate students.

1. Title of the project: To obtain the speed and position response of a dc motor.

2. Rationale of the project: To give hands-on experience in analyzing the system components and experimenting with various feedback control schemes.

3. Objectives of project: a. To provide an in-depth description of dc motor speed response, speed control, and position control concepts.b. To provide preliminary instruction on how to identify the parameters of a system.c. To show how different parameters and nonlinear effects such as friction and saturation affect the response of the motor.d. To gain practical knowledge of MATLAB software.

5. Resource/material required:a. A dc motor. b. A power supply and amplifier to power the motor. c. Interface cards to monitor the sensor and provide a command voltage to the amplifier input and a PC running MATLAB and Simulink to control the system and to record the response.

6. Methodology/procedure/approach (Step by step):a. To control the position of the motor shaft, the simplest strategy is to use a proportional controller with gain K. The block diagram of the closed-loop system is shown in figure.

b. The system is composed of an angular position sensor (usually an encoder or a potentiometer for position applications). c. For simplicity the input voltage can be scaled to a position input Tin(s) so that the input and output have the same units and scale.

Assignment No.4: Case StudyDate: 11.03.2015PART I:Consider the system in figure 4.1.

Figure 4.1

The purpose of the system considered here is to control the positions of the fins of a modern airship. Due to the requirements of improved response and reliability, the surfaces of modern aircraft are controlled by electric actuators with electronic controls. Gone are the days when the ailerons, rudder, and elevators of the aircraft were all linked to the cockpit through mechanical linkages. The so-called fly-by-wire control system used in modern aircraft implies that the attitude of aircraft is no longer controlled entirely be mechanical linkages. Figure 4.1 illustrates the controlled surfaces and the block diagram of one axis of such a position-control system. Figure 4.2 shows the analytical block diagram of the system using the dc-motor model. The system is simplified to the extent that saturation of the amplifier gain and motor torque, gear backlash, and shaft compliances has all been neglected. However, when you get into the real world, some of these nonlinear effects should be incorporated into the mathematical model to come up with a better controller design that works in reality. The objective of the system is to have the output of the system, follow the input.
