This video is part of the Module 7: Torque Control Workshop module and shows how to implement a FOC and control the PMSM torque and flux using standard PI controllers. This method is used to spin the PMSM in open loop using Space Vector Modulation. The video shows how to implement a control system with two control loops: FAST and SLOW
This video is part of the https://community.nxp.com/thread/467938 Workshop module and shows how to implement a simple V/F (V/Hz) scalar control to spin the PMSM in open loop using Space Vector Modulation and trapezoidal speed profile.
This video explains how to use a three phase inverter to control the voltage applied on PMSM using various PWM Modulation techniques like: bipolar modulation unipolar modulation sinusoidal modulation space vector modulation third harmonic injection The goal of this video is to cover the topic of Space Vector Modulation and PWM generation that represents the basics for applications we are going to develop throughout https://community.nxp.com/thread/464336 .
This video explains the steps required to build a control system based on Field Oriented Control theory. Step by step it is shown how the Park and Clarke Transformations works, how the values on stationary vs. rotating frames look like and what does it takes to build a digital control system around FOC concepts with S32K144 Evaluation Board
This video explains the basics of the Permanent Magnet Synchronous Motors modes of operation with Field Oriented Control. It is not intended to replace a good engineering handbook and to go thru all the details of construction or mathematical models of the PMSM. The topics highlighted in this video are chosen to provide specific details that represents the basics of PMSM motor control theory. The goal of this video is to refresh your knowledge about the motors and to explain some key aspects of the theory behind PMSM and Field Oriented Control that we are going to use in the next modules of the https://community.nxp.com/thread/464336
This video shows how to build a simple S32K application with NXP's Model-Based Design Toolbox that consists in: Read the SW2 push button state at each 0.1 seconds Switch on/off the Blue LED Record the value of the push button and display its state via serial communication in FreeMASTER
This video shows how to navigate within the integration Matlab help for NXP's Model-Based Design Toolbox for S32K1xx. The following items will be highlighted: Getting HELP Open Examples Support via Community
This video shows the overall motor control application developed with Model Based Design Toolbox. We are going to assemble all the blocks developed throughout this course and we will have the motor running under Speed Controller supervision. We also discuss about the FreeMASTER and you can easily create nice control panels for the applications and how you can validate the Speed Controller and overall Motor Control application. We discuss about: - Speed Controller implementation in Simulink for real time systems; - Motor and Inverter protection for over-current, over- and under-voltage; - FreeMASTER control panel using HTML and Java Script; - Various tests on the MPC5744P DevKit and MotorGD DevKit; NOTE: Chinese viewers can watch the video on YOUKU using this link 注意：中国观众可以使用此链接观看YOUKU上的视频
In this video we discuss about control system theory and the mathematics behind the speed controller designing process. We are going to analyse the control system stability based on poles and zeros location and then we will compute the PI speed controller gains using the Root Locus allocation method. For the cases where the system transfer function is unknown we are discussing Ziegler Nichols method for finding the controller gains and we are going to verify the control system designing process by simulating a BLDC motor behavior and building a PI speed controller to handle the system response. We discuss about: - How to choose the controller type based on system transfer function; - How to analyze system stability starting from the characteristic polynomial; - What are the gain, zeros and poles of closed loop transfer function; - Root Locus allocation method based on second order ideal model with dumping factor and natural frequency; - Ziegler Nichols tuning methods; - Simulink models for BLDC motor and PI Speed Controller NOTE: Chinese viewers can watch the video on YOUKU using this link 注意：中国观众可以使用此链接观看YOUKU上的视频
In this video we show how to build, simulate and test a speed estimator based on Hall Sensors for a BLDC motor. The estimator is first tested under Matlab Simulink environment and then ported into the Open Loop Control Simulink model and tested on the MPC5744P Development Kit with FreeMASTER over CAN interface. We discuss about: - How to compute the speed; - How to build a speed estimator based on Hall sensors; - Step-by-step model building an enhancements; NOTE: Chinese viewers can watch the video on YOUKU using this link 注意：中国观众可以使用此链接观看YOUKU上的视频
In this video we discuss about Open Loop Control strategy and for the first time in this course we will put together all the models we have created so far and build the Simulink model that will allow us to rotate the BLDC motor. We discuss about: - Open Loop Control diagram; - Step-by-step model building an enhancements; - Test the open loop control system on the BLDC motor; NOTE: Chinese viewers can watch the video on YOUKU using this link 注意：中国观众可以使用此链接观看YOUKU上的视频
