Sample Question 1
Question
A graduate student is working on modeling and simulation for an automated vehicle system. They are expected to design a mathematical model for path tracking control using a proportional-integral-derivative controller. The student is unsure how to select appropriate parameters for different environmental conditions and test the robustness of their model. Explain the recommended approach.
Expert Answer
When working on path tracking control using a proportional-integral-derivative controller, the first step is to define the system's dynamics clearly. Begin by identifying the kinematic model of the vehicle in terms of its longitudinal and lateral motions. In MATLAB, this model can be implemented using basic control toolboxes.
To tune the controller parameters appropriately, simulation plays a vital role. We suggest starting with the Ziegler-Nichols method for an initial estimate and then using MATLAB’s PID Tuner for refinement. This allows real-time visual feedback and sensitivity analysis under different conditions such as road curvature or wind resistance.
Robustness testing involves running simulations for a range of environmental variables—like uneven terrain, sensor delays, and speed variation. Use Monte Carlo simulations in MATLAB to observe the consistency of the controller's output under uncertain scenarios.
This approach not only builds a strong foundational model but also prepares the student to adapt the controller to real-world challenges in intelligent vehicle design.
Sample Question 2
Question
A master's student is analyzing real-time electrical signals for fault detection in a three-phase power system. They need to apply a signal processing technique to extract key features and identify disturbances. Describe an effective method using MATLAB and explain why it is suitable.
Expert Answer
For real-time signal analysis in a three-phase power system, Discrete Wavelet Transform (DWT) is one of the most effective techniques. It enables decomposition of complex signals into components at various frequency bands, which is ideal for detecting transient faults like short circuits or voltage sags.
In MATLAB, the Wavelet Toolbox offers a comprehensive set of functions to apply DWT. Begin by selecting an appropriate mother wavelet (e.g., Daubechies or Symlet) that aligns with the signal type. The student should then decompose each phase signal using multi-level wavelet analysis. The resulting coefficients can be analyzed to observe sudden spikes or drops, which typically correspond to faults.
This method is suitable because it allows time-frequency localization, which is crucial in systems where fault duration is very short. Unlike Fourier-based approaches, DWT is better equipped to detect abrupt signal changes, making it reliable for protective systems in power engineering applications.
