The software works by utilizing a "FAST" (Flux, Angle, Speed, Torque) software observer. This observer resides in the ROM of specific C2000 chips or is provided as a library. It identifies the motor parameters—such as resistance, inductance, and flux—automatically during a "motor identification" routine. This eliminates the need for manual parameter entry and complex tuning of the estimator. Modular Hardware Abstraction Layer (HAL)
The SDK is designed to work seamlessly with Code Composer Studio (CCS). It includes a variety of "Labs" or project examples that guide users through a step-by-step development process:
At its core, the Motor Control SDK is built upon C2000Ware, the foundational software stack for all C2000 MCUs. It utilizes a layered approach to ensure code portability across different hardware generations, such as the F28004x, F2838x, and F28002x series. c2000ware motor control sdk work
The Texas Instruments C2000Ware Motor Control SDK is a comprehensive software package designed to reduce development time for three-phase motor control applications. It provides a highly structured environment for engineers working with C2000 real-time microcontrollers, offering everything from low-level drivers to sophisticated sensorless control algorithms.
Clarke and Park Transforms to convert 3-phase signals into 2-phase DC values. PI (Proportional-Integral) controllers for torque and flux. The software works by utilizing a "FAST" (Flux,
The SDK functions through a strictly timed execution model. The motor control "inner loop" is typically triggered by a PWM interrupt. When the PWM counter reaches a specific point, it triggers the ADC to sample phase currents. Once the conversion is complete, an interrupt is fired, and the SDK’s control software takes over. Inside this interrupt, the SDK executes:
To enhance the workflow, the SDK works in tandem with TI Universal Motor Lab and MotorStudio. These graphical user interfaces connect to the running MCU via JTAG. They allow developers to visualize phase currents, adjust Kp/Ki gains in real-time, and monitor the FAST observer’s performance without recompiling code. This eliminates the need for manual parameter entry
This abstraction allows developers to move their motor control logic from one TI evaluation board to a custom PCB with minimal changes to the core application code. The Control Loop Execution
