ENSC 387 (04-3)

Introduction to

Electromechanical Sensors and Actuators

SFU crest


Course Description

This course provides an introduction to the theory and application of sensors and actuators for electromechanical, computer controlled-machines and devices. Topics include operating principles, design considerations, and applications of analog sensors, digital transducers, magnetic circuits, stepper motors, continuous-drive actuators, and drive system electronics. Component integration and design considerations are illustrated through examples selected from applications of machine tools, precision machines, robotics, aerospace, and transportation. Laboratory exercises strengthen the understanding of component performance, system design and integration.


Course Objectives

This is a core course in the Systems Option introducing control instrumentation for the design and integration of computer-controlled machines and devices. It is intended to build on material learned in ENSC 383, complement ENSC 340/440, and provide a foundation for advanced systems topics in ENSC 483 and ENSC 488. It also offers valuable background for students in related programs such as engineering physics and biomedical engineering.


Prerequisites

ENSC 383 or a first course in feedback control systems.

Homework Policy

Homework and laboratory assignments will be distributed 1-2 weeks prior to the due date. To receive full credit, the completed assignments should be submitted by the due date. Late assignment will be accepted if an e-mail request has been sent to Dr. Gruver before the due date with the reason for the delay and date when it will be sumitted.

Class and Exam Attendance

You are responsible for all activities conducted during the scheduled class period, including announcements that may be given. Failure to take the mid term exams during the assigned class period will result in a grade of zero being recorded unless you have personally contacted me before the exam. Make-up exams may be given, but only under exceptional circumstances.


Additional Comments

Course Web Page: Please check this page frequently for information concerning the course.

Assignment Policy: Homework and laboratory assignments will be available for download from the course web page at least one week prior to the due date. Completed assignments should be submitted to the TA by 4PM on the due date. If it will be necesssary to submit your assignment late, send an e-mail to the TA prior to the due date. Include the reason for the delay and the date when you plan to submit the assignment. Failure to comply with this rule may result in a mark of zero being recorded. Late submissions will not accepted after the tutorial session.

Exam Attendance: Failure to take the mid term exams or the final exam during the assigned class period will result in a mark of zero being recorded unless you have contacted Dr. Gruver before the exam. Make-up exams will be given only under exceptional circumstances.

E-mail: Check your e-mail daily for messages concerning class meetings, exams, homework, lab assignments.

Lectures: You are responsible for all business conducted during the scheduled class period, including announcements that may be given.

Homework: The homework assignments are intended to reinforce the major concepts and to serve as a measure of how well you understand the course. The homework, however, is not necessarily representative of questions that will be asked on the exams.

Labs: Laboratory experiments are an essential part of this course because they will provide you with practice in the control of physical systems. Exercises will be assigned using equipment in the lab. You may work in groups of 3 persons and submit one report for your group. Your report must be limited to 10 pages and include your data. Additional pages may be disregarded by the TA.

Exams: It is very important that you understand the concepts covered in this course. I will try to design the exams so that comprehension of the material is emphasized, not merely memorization. You may bring to the exams one 8.5"x11" page with handwritten notes on either side. You may use pencil rather than pen for writing the exam. You must show all work on an exam to receive full credit.
