Question 1 – Signal Analysis in a Noisy Environment

A research student working on biomedical signal processing encountered a problem involving the extraction of a clean signal from a noise-affected ECG dataset. The dataset showed inconsistent waveform patterns due to motion artifacts and baseline drift. The student was required to develop a solution that would preprocess the signal, remove the noise, and then visualize the clean output.

Expert’s Solution:

Our expert began by thoroughly analyzing the dataset to identify the type of noise present. In this case, it included low-frequency baseline drift and high-frequency motion artifacts. A two-stage filtering approach was adopted. The first stage involved the use of a high-pass filter to remove the baseline drift, and the second stage applied a low-pass filter to eliminate the high-frequency noise.

Once the filters were defined based on suitable cut-off frequencies, the student was guided through how to apply these filters sequentially to the ECG data. The expert then assisted in plotting both the raw and filtered signals to visually compare the improvement. Additional smoothing using a moving average technique was suggested to enhance clarity.

This solution not only helped the student understand how to deal with real-world signal imperfections but also gave them confidence in interpreting the results in a clinical context.

Question 2 – Optimization of a PID Controller for a Dynamic System

A postgraduate student working on control engineering had to optimize a PID controller for a nonlinear dynamic system. The system was not responding well to traditional tuning methods, and the student was asked to implement an adaptive control technique that would automatically tune the PID parameters for optimal system behavior.

Expert’s Solution:

Our specialist approached this task by first helping the student model the dynamic system accurately. Since the system’s behavior varied with time and external disturbances, a static PID was inadequate. Therefore, an adaptive PID structure was proposed where the gains were updated in real time based on the system’s performance.

Using performance indices such as Integral of Time-weighted Absolute Error (ITAE), the expert helped design a logic that would tune the controller gains dynamically. A simulation environment was then developed to test various scenarios including setpoint changes, load disturbances, and initial transients.

The student was provided with a clean, structured solution that not only met academic expectations but could also be extended to real-world industrial applications. More importantly, the expert included an explanation of how adaptive control improves stability and accuracy in dynamic systems, helping the student grasp the conceptual depth of the topic.
