Controlling the Vehicle’s Active Suspension System Using State Vector Feedback Control

• Course Name: Modern Control I (Master Studies)
• October 2018 - November 2018

• Project Codes

This course project considers a quarter-car vibrational model with an input force and output displacement. The goal is to simulate the open-loop system and design various classical controllers (P, PI, PID) as well as an advanced state-vector feedback controller (SVFC). A full-order state observer is used in the advanced control system to estimate the system states.

• Simulate the open-loop system response under initial conditions.
• Design and implement classical controllers (P, PI, PID) to satisfy design requirements:
• Settling time less than 5 seconds for a step input.
• Maximum overshoot limited to 10%.
• Zero steady-state error (or maximum 1% if present).
• Design an advanced state-vector feedback controller (SVFC) if possible and implement it to meet the above requirements.
• Select the most suitable controller and justify the choice.
• Design a full-order continuous-time state observer to estimate system states and validate its performance.
