Control System Analyzer (MATLAB)

A MATLAB App Designer application for analyzing continuous-time control systems through transfer functions.

Features

• Transfer function input

• Pole and zero calculation

• Automatic system classification:

  • Stable
  • Unstable
  • Underdamped
  • Critically damped
  • Overdamped

• Damping ratio (ζ) estimation

• Step response analysis

• Rise time calculation

• Settling time calculation

• Overshoot calculation

• Gain margin calculation

• Phase margin calculation

• Bode plot visualization

• Root locus visualization

• Pole-zero map visualization

Requirements

• MATLAB R2024b or newer
• Control System Toolbox

Usage

1. Enter a transfer function using MATLAB syntax.
2. Click Analyze.
3. Explore the generated plots through the application tabs.

Example

1/(s^2+3*s+2)

Future Improvements

• PID controller design
• Report export
• System comparison
• Closed-loop analysis
