Mechatronics System Control

Study Notes

Introduction to Mechatronics

Mechatronics is the synergistic use of precision engineering, control theory, computer science, and sensor and actuator technology to design improved products and processes.
It is an interdisciplinary field of engineering that deals with the design of products whose function relies on the integration of mechanical, electrical, and electronic components connected by a control scheme.

Definition of Mechatronics

Mechatronics combines electronics and mechanical components with modern controls and microprocessors.
It involves the analysis, design, synthesis, and selection of systems that combine electronics and mechanical components.

Objectives of Mechatronics

To improve products and processes.
To develop novel mechanisms.
To design new products.
To create new technology using novel concepts.

Sensors

A sensor is a device that responds to a change in the physical phenomenon.
Sensors are required to monitor the performance of machines and processes.
Transducer is a device that converts one form of energy into another form of energy.
Common measurement variables in mechatronics systems are temperature, speed, position, force, torque, and acceleration.

Various Sensors

Proximity sensors
Limit switches
Potentiometer
Digital optical encoder
Strain gage
Load cells
Linear variable differential transformer
Bimetallic strip
Thermocouple
Accelerometer

Hall effect sensor
Resistance temperature detector

Use of Sensors/Transducers

To provide information of the measuring element.
To act as a protective mechanism for the system.
To help eliminate redundant devices.
To act as a feeding or sorting device in complex systems.

Key Elements of Mechatronics

Models: collections of mathematical and logic expressions that accept external information and process it to produce outputs.
Block diagram: consists of two fundamental objects, signal wires and blocks.
Signal wire: transmits a signal or a value from its point of origination to its point of termination.
Blocks: get input and produce output.
Simulation: the process of solving the model, performed on a computer, and can be divided into three sections: initialization, iteration, and termination.
