MECHATRONICS AND

CONTROL ENGINEERING

By Kyle Jiang

Department of Mechanical Engineering

Office: F36

Email: k.jiang@bham.ac.uk

This module is a combination of “Mechatronics” and “Control

Engineering”.

1.1 Teaching arrangement

Mechatronics will be delivered in the first five weeks, and

Control Engineering will be delivered in the latter five weeks.

1.1.1 Teaching Outcome of Mechatronics:

(Control Engineering part will be introduced in Week 7)

Students will

understand the concept and working principle of

mechatronic systems correctly;

have the knowledge in popularly used mechatronic

components;

be able to use the concept of mechatronic systems in

engineering designs.

1. INTRODUCTION TO THE MODULE

1.1.2 Reference books of Mechatronics:

The Principle of Computer Hardware, Fourth edition, by Alan Clements,

Oxford University Express, 2006

Mechatronics and the Design of Intelligent Machines and Systems, by

D.A. Bradley, etc., CRC Press, 2000

Mechatronics, by W. Bolton, Fifth edition, Pearson, 2011

1.1.3 Past exam papers of Mechatronics

Available via my.bham Exam Past Papers under titles:

A22282 LI Applied Mechanics II (2009-10)

1.1.4 Delivery and Assessment of Mechatronics

– Lectures: Recorded lectures will be uploaded to Canvas

by each Monday and Thursday of the semester, except

Week 6, which is a reading week.

– 1.5 hour MCQ test for Mechatronics in the beginning of

Week 7 (50% of the module) and 1.5 hour written exam

for Control Engineering in May.

– Labs are suspended in this year.

1.2 Introduction to Mechatronics (Mechanical + Electronics)

Mechanical Engineering (drive) + Electronic Engineering

(sensing & control)

Definition by Industrial Research and Development Advisory

Committee of the European Community: Mechatronics is the

synergistic combination of precision engineering, electronic control and

systems thinking in the design of products and manufacturing processes.

Mechatronic systems can be:

– Intelligent (AI),

– High precision,

– Compact,

– And cost effective.

MECHATR

Mechanical system: Watt’s fly-ball governor

Mechatronic system: sensor + control + motor

Tachometer

(sensor)

ADC and

controller

Motor (actuator)

An example of speed control:

A mechatronic example:

A robot manipulator

– Six joints for six degrees of freedom to reach

any position in any orientation;

– Each joint has a motor, a sensor, and a

microprocessor for precision control of

positions;

– A central computer does kinematic

calculations and coordinates the movement

of every joint.

Mechatronic Systems and their contents:

A typical mechatronic system has a mechanical

drive, sensors, and a control unit. Communications

and display systems are optional.

Sensors and Transducers:

- Sensors: devices which measure and respond to a

particular change.

- Transducers: devices which convert energy from one

format into another.

- In many cases, sensors can be called transducers.

Control devices

- for information processing & decision making.

- Logic circuits, microprocessors/computers,

feedback controllers, op-amps, switches and

amplifiers.

Actuators

- electric motors, stepper motors, pneumatic

and hydraulic systems.

- Heaters, compressors, pumps, fans,

government policies

Teaching Flow Chart:

1. Introduction to

Mechatronics

3. Sensing Unit

2. Control

Unit 4. Drive Unit

5. Mechatronic

Systems Design

6. Summary

2. Digital Logic and Boolean Algebra

2.1 Fundamental Gates

AND, OR, NOT, NAND, NOR, EOR, and EXNOR.

The concept of a gate: It takes in a combination of

inputs (1 or 0), but produces either 1 (on) or 0 (off).

Gate names: Each gate name indicates a condition on

which the gate produces 1.

Applications: digital logic gates form the fundamental

components of computers.

Section I. Control Devices and Systems

A 4 bit ALU

Circuit.

An op-amp chip.

Seven essential gates:

– Three Basic Gates: AND, OR, NOT

– Two Derived Gates: NAND, NOR

– Two Exclusive Gates: XOR, XNOR

Truth tables: To list the complete logic possibilities and

results of logic devices and circuits.

Q: What gates do the following truth tables represent

respectively?

2.2 Logic gates and truth tables

XNOR

XOR

Op-amp comparator

– An op-amp voltage comparator compares the

magnitudes of two voltage inputs and outputs a digital

signal indicating which is larger.

– An illustration of the property of a comparator:

Q: Design a safety circuit for a high pressure plant using

logic gates and comparators. When either temperature or

pressure is higher than required,. The plant will be shut

down.

An example of logic gate applications

Example: If A=1010 and B=0001 in data registers, A + B = ?

If data register D1 stores A=1011 0110, and data register D2

stores B=1001 1101, find the results of the following operations

in a computer:

(a) A · B=?

(b) A+B=?

(c)

Solutions:

(a) 1001 0100

(b) 1011 1111

(c) 0100 0000

A logic operation example in programming
