Motor Control Design Suite

Design a motor control system with less effort.

PSIM’s Motor Control Design Suite gives you the toolbox to design a motor drive system with greater efficiency and less effort.

Fueled by design templates, automated controller design, and the capacity to evaluate interactions between major subsystems, PSIM’s Motor Control Design Suite provides a nimble solution to an otherwise complicated task.

 

Specify and design motor drives using your choice of templates.

The motor control design suite includes templates for the control of PMSMs and induction machines. For PMSMs, there are options that cover most design scenarios of:

  • surface magnets (SPM/BLDC)
  • Interior magnets (IPM)
  • Sensored control
  • Sensorless control (InstaSPIN)
  • Speed control
  • Torque control
  • Non-ideal magnetics (Ld, Lq)

 

The design suite will implement Field Oriented Control, with SVPWM with Max-Torque-per-Ampere control, Field Weakening, and Max-Torque-per-Volt Control. Digital PI controllers for Id, Iq, and the speed loop are properly defined.

The output from the design suite is a fully defined simulation with inner and outer control loops that will work at the frequency the user specifies. The output can be used as-is for simulations or modified by the user to match their simulation requirements.

Motor Control Design

Swift Motor Control Design

The user defines the high-level system input specifications:

  • Vdc bus
  • Motor parameters
  • Switching and control frequencies
  • Maximum inverter current
  • Desired control bandwidth

After a few mouse clicks, the design suite uses the user-defined parameters to close the control loops and generate a simulation that is ready for further analysis.

 

 

The output of the design suite is a simulation that includes a DC bus, 3 phase inverter, motor, motor control, and a mechanical load.

 

Motor drive analysis made easy

Closing the control loops for Id, Iq, and speed/torque is not an easy task. Also, the proper implementation of field weakening, Max-Torque-per-Ampere control, and Max-Torque-per-Volt control can be very challenging. With the Motor Control Design Suite, you can easily see the impact of these advanced motor control algorithms as they greatly expand your possible torque/speed operational envelope.

Sensorless control made easy

Determining the shaft position of a motor through sensored feedback or sensorless internal calculation both pose unique challenges. Sensorless control can be especially difficult with countless papers on low-speed operation, synchronization, among other topics. Typical implementations use a sliding mode observer, SMO, which can be a bit of “guess and test” to setup. Texas Instruments also has a proprietary sensorless algorithm, InstaSPIN, which is very robust & powerful and addresses many of the issues faced by SMO implementations. The issue with InstaSPIN is that there are many parameters it requires and simulating its operation is only possible through a Processor-in-the-loop (PIL) simulation.

Our Motor Control design suite easily takes your machine and hardware parameters and converts them into the parameters that InstaSPIN requires. Further, with our PIL module, you can easily simulate its operation. This combination of functionality allows you to easily implement one of the most robust and powerful sensorless control algorithms available.

Digital control, implementation, and code generation

Our Motor Control Design Suites implement digital control, z-domain, based PI controllers. The user can select different execution rates for the switching PWM, inner current loops, and outer torque or speed loops. The control algorithm can be easily implemented on a MCU with our embedded code generation options. For a sensorless implementation with InstaSPIN, the design suite will design a code-generation-ready simulation that will run without modification on TI launchpadXL development hardware.
