PID Control of a Vienna Rectifier-Based Power Factor Corrector

Learn how to automatically tune the DC-link voltage, DQ-axis current, and voltage neutral controllers for a Vienna-rectifier-based power factor corrector modeled in Simscape Electrical™. Use the Closed-Loop PID Autotuner block to tune controller gains to provide fast and stable tracking of the DC-link output voltage to variations in load. The block injects an excitation signal during closed-loop plant operation to estimate plant frequency response. Use the obtained frequency response to automatically compute PID gains. See how to use the Closed-Loop PID Autotuner block on the inner DQ-axis current loops, the outer DC-link voltage loop, and the voltage neutral loop. Use the computed PID gains to update parameters of the PID controller in the model. Finally, see how to verify controller performance by running closed-loop simulation.

What Is Reinforcement Learning Toolbox?

Reinforcement Learning Toolbox™ provides an app, functions, and a Simulink® block for training policies using reinforcement learning algorithms, including DQN, PPO, SAC, and DDPG. You can use these policies to implement controllers and decision-making algorithms for complex applications such as resource allocation, robotics, and autonomous systems. The toolbox lets you represent policies and value functions using deep neural networks or look-up tables and train them through interactions with environments modeled in MATLAB® or Simulink. You can evaluate the single- or multi-agent reinforcement learning algorithms provided in the toolbox or develop your own. You can experiment with hyperparameter settings, monitor training progress, and simulate trained agents either interactively through the app or programmatically. To improve training performance, simulations can be run in parallel on multiple CPUs, GPUs, computer clusters, and the cloud (with Parallel Computing Toolbox™ and MATLAB Parallel Server™). Through the ONNX™ model format, existing policies can be imported from deep learning frameworks such as TensorFlow™ Keras and PyTorch (with Deep Learning Toolbox™). You can generate optimized C, C++, and CUDA® code to deploy trained policies on microcontrollers and GPUs. The toolbox includes reference examples to help you get started.

How to Debug MATLAB Code

Learn about the built-in MATLAB® debugger tools, which help catch bugs while coding. The video begins by explaining the types of bugs you may encounter while coding. You then see how to use MATLAB to examine error messages and use the debugger tools (breakpoints, step, continue, etc.) to identify where bugs are occurring. To illustrate these debugging techniques, the video uses code for calculating the 10th Fibonacci number. You’ll see an example of the types of errors, and you’ll learn how to correct them based on what is present in the MATLAB user interface. You’ll also get an overview of other best practices for debugging settings. This video was created as part of the MATLAB student ambassador program: https://bit.ly/36BoXdE Check out the full playlist, which shows how to use MATLAB and Simulink across a range of topics: https://youtube.com/playlist?list=PLn8PRpmsu08oBSjfGe8WIMN-2_rwWFSgr Additional Resources: Debug a MATLAB Program: https://bit.ly/3kqfv33 Debugging and Analysis Documentation: https://bit.ly/3qXT73p -------------------------------------------------------------------------------------------------------- Get a free product trial: https://goo.gl/ZHFb5u Learn more about MATLAB: https://goo.gl/8QV7ZZ Learn more about Simulink: https://goo.gl/nqnbLe See what's new in MATLAB and Simulink: https://goo.gl/pgGtod © 2021 The MathWorks, Inc.

Part 2: Phase I - Modeling Steady State Conditions

This is part 2. See part 1 here: https://youtu.be/4kNBxqG9jF4 The goal of process monitoring is to ensure that the planned operations are successful. You can achieve this goal by recognizing process upsets and faults using data-driven measures, such as PCA. These measures are derived directly from process data and aid in fault detection and diagnosis by transforming the high dimensional data into a lower dimension, and thereby capturing important information in the process. Create a PCA model to describe the normal variability in the operation of a methanol-ethanol distillation column. Building an effective monitoring system requires a good data set that represents the steady state, normal operating conditions. Use an application developed in MATLAB® by GIEM as an aid for understanding the PCA-based MSPC strategy.
