Review Questions

• How does MATLAB facilitate the application of the root locus technique in control system design?
  • MATLAB simplifies the application of the root locus technique through its Control System Toolbox, which includes functions specifically designed for plotting root loci. Users can input transfer functions directly and use commands like `rlocus` to visualize how the poles move in response to changes in gain. This visual representation helps engineers understand stability and performance as they design control systems.
• In what ways can MATLAB enhance the tuning process of PID controllers during design?
  • MATLAB enhances PID controller tuning by providing interactive tools such as the PID Tuner app that allows users to simulate how different tuning parameters affect system response. Users can experiment with proportional, integral, and derivative gains while observing step responses or frequency responses in real-time. This feedback loop streamlines the tuning process, making it easier to achieve desired performance metrics without extensive trial and error.
• Evaluate the impact of using MATLAB for simulating electromechanical systems on engineering education and research.
