overview

field-oriented control is a popular means of controlling brushless motors used in automotive, industrial, aerospace, and consumer applications. motor control blockset for simulink speeds up the development of a field-oriented controller by helping you to verify control algorithms using simulation and generate compact and efficient code for a microcontroller. in this session, mathworks engineers will walk you through a reference example of field-oriented control algorithm simulation and code deployment to a ti c2000 microcontroller for a permanent magnet synchronous motor (pmsm).  during the demonstration, we will show how motor control blockset can be used to:

• parameterize a pmsm model by running instrumented tests on a motor
• model motor and inverter dynamics at different levels of fidelity
• design a field-oriented controller, including current, and torque/speed loops using a quadrature encoder or hall sensor
• show sensorless control using a flux observer
• demonstrate field weakening control to exceed the rated speed of the motor
• use automatic pid tuning to set the controller gains for current and speed loops
• verify controller performance through closed-loop simulations
• generate code for a texas instruments c2000 microcontroller and operate the current loop of the pmsm at 20 khz
