LAB # 5 AC STATOR CURRENT CONTROL Please reach out for any extensions. The purpose of this experiment is to use a microcontroller to control the three-phase stator currents of an AC machine. In this lab, the DC machine will be used to prevent the rotor of an AC surface- mount permanent-magnet machine from spinning. As a result, the machine will behave as the three-phase AC stator discussed in the lecture. The required material Based on our experience in previous lab experiments, we can realize how difficult it would be if we wanted to control a three phase machine using breadboard circuitry. In this lab we will therefore be taking advantage of microcontroller-based control systems that we used in lab 6, the dSpace controller. In this experiment we are replacing one of the DC machines with a Surface- Mount Permanent-Magnet machine with the following parameters: Ld = 0.09 mH, Lq = 0.27 mH and R = 300 m Remote students (ISD 599) will be watching the video of the lab demonstration: Lab 05: AC motor current control Please watch the Lab 05: AC motor current control video under Panopto video section on canvas. After watching the lab performance video, please use the provided experimental data on canvas to analyze and answer the post lab questions. Please note: • The instructor in the video is not me, It's an old video. EECS-419 Winter 2024 Part B, Lab Report Your lab report should describe the experiment in detail, so that the reader can establish that you understood the lab. You should compare the results of the stationary and synchronous current regulators, and explain the observations/differences. Please use the data provided on canvas to plot/analyze the response for both regulators. The file name indicates excitation frequency and the controller type. Further, a document containing the label for the reference data is also shared to help in identifying the recorded signals. A sample code illustrating on how to read the “.mat” file is also provided. Please state whether the results agree with your understanding of the theory. Pre-Lab Design PI regulators for both stationary and synchronous reference frames for the given machine parameters and a desired bandwidth of 500 Hz. Also, study the design of current regulators in synchronous frame and stationary reference frames (you will have to submit the control block diagram for both). You will not be able to do the understand/analyze experiments without the knowledge of these controllers. 2
