This page describes the *EEGR3523 Mechatronics* class that was taught in the spring of 2019 at LeTourneau University. This is an undergraduate class that introduces system modeling, control systems, and electric machines.

**Textbooks:** *Mechatronics--An Integrated Approach*, C. de Silva, CRC Press, 2005.
*Electric Machines and Electromechanics*, 2nd edition, Schaum's Series, S. A. Nasar, McGraw-Hill, 1997.

**Homework:** Weekly homework sets were assigned. Two homework problems refer to the MATLAB and Simulink files solveexample.m and state_intro.mdl.

**Lectures:** The class had two weekly 80-minute lectures. Each of the three main topics of the class (modeling, control systems, and electric machines) was covered for about one third of the semester. The following were addressed:

- Basic Electrical and Mechanical Components.
- Equations in the Time Domain and the Laplace Domain.
- Motion Mechanisms.
- Review of the Laplace Transform.
- Transfer Functions.
- Transient Response and Steady-State Response.
- State-Space Models.
- Block Diagrams.
- Mason's Gain Formula.
- Introduction to Control Systems.
- Stability. The Routh-Hurwitz Criterion.
- Controller Design for Steady-State Specifications.
- First and Second Order Systems. Controller Design for Time-Response Specifications.
- First and Second Order Approximations.
- The Root Locus.
- Nyquist Plots.
- Bode Plots.
- Controller Implementation. Operational Amplifiers.
- DC Machines.
- AC Machines.
- Induction Motors.
- Stepper Motors.

Slides for: Modeling, Review of the Laplace Transform, Transfer Functions and System Responses, The State-Space Model, Control System Stability, Compensating Error, Time-Response Specifications, DC Machines.

Handouts: Basic Components, The Laplace Transform, Basic Operational Amplifier Circuits, The Root Locus.
