Mechatronics Essentials: Foundations of Sensing, Electronics, Actuation, and Control

Mechatronics Essentials is a figure-first textbook for undergraduate students in Mechanical, Electrical, and Computer Engineering. Organized around a five-block mechatronics architecture, it connects analog and digital electronics, sensors, actuators, and control system design into a single coherent path from physical signal to digital control and back.Chapters cover analog circuits and devices, digital logic and microcontroller architecture, ADC/DAC conversion, sensors, actuators, and classical and modern control (PID, pole placement, LQR/LQI), with worked examples, circuit diagrams, and MATLAB/Simulink models throughout. Appendices introduce C programming for embedded systems and MATLAB/Simulink fundamentals.Suitable as a standalone mechatronics course text or as a supplement to existing circuits, controls, or embedded systems courses.
