MATLAB Programs for Mechatronic Control Engineering Experiments

Mechatronic control engineering experiments significantly enhance students' understanding of control systems through practical investigation. The experimental platform provides GUI-based programs implementing the following four core experiments:

1. Time Domain Response Analysis Experiment: This module enables students to analyze temporal characteristics of mechatronic control systems, including transient response and steady-state performance. The GUI likely implements numerical integration methods (e.g., Runge-Kutta) and system simulation algorithms using MATLAB's control system toolbox functions like step(), impulse(), and lsim().

2. Frequency Domain Characteristics Analysis Experiment: Students explore system behavior in frequency domain, examining amplitude-frequency and phase-frequency characteristics. The code probably utilizes FFT algorithms and Bode plot functions (bode(), nyquist()) with interactive parameter tuning capabilities.

3. Stability Analysis Experiment: This component focuses on system stability criteria and determination methods. The implementation likely incorporates root locus plots (rlocus()), Routh-Hurwitz stability criterion algorithms, and stability margin calculations through margin() function.

4. Correction Design Experiment: Students learn compensation design methodologies including model establishment and correction method selection. The GUI probably features PID tuning algorithms, lead-lag compensator design, and interactive block diagram simulations using Control System Designer tools.

The platform provides complete MATLAB GUI source code (possibly developed using App Designer or GUIDE) and compiled executable files for all four experiments. Through these hands-on experiments, students deepen their understanding of mechatronic control engineering while developing practical skills and innovative capabilities.
