MATLAB Quarter Car Model Controls

Active Suspension System — Quarter-Car Model (MATLAB + Simulink)

Designed a feedback controller for an active car suspension system using MATLAB and Simulink, with the goal of minimizing vehicle oscillations and thus enhance theoretical passenger comfort.

Highlights

  • System Modeling: Constructed a quarter-car model and derived transfer functions using Laplace transforms to represent the relationship between actuator input, disturbance forces, and system response.
  • Control Design: Applied classical control methods -> Bode plots, Nyquist diagrams, and root locus—to develop controllers that met performance specs (e.g., <5% overshoot, <1s settling time).
  • Simulation & Optimization:
    • Used MATLAB’s SISOTOOL for fine-tuning the compensator.
    • Achieved smooth system responses to road disturbances with minimal residual oscillations.
