Motor control system based on ADSP-CM408

For motor control systems, ADI can provide complete solutions covering all important devices in the signal chain. Related products include analog-to-digital/digital-to-analog converters, amplifiers, embedded processors, iCoupler® digital isolators, and power management devices. These high-performance devices and increased system integration help achieve newer topology designs and bring value to customers' differentiated system designs.

The ADSP-CM4xx mixed-signal control processor uses the ARM Cortex M4 processor core and integrates high-precision ADC, digital accelerators and filters, SRAM and flash memory, and rich peripherals. ADSP-CM4xx processors are suitable for a wide range of embedded applications requiring high-performance real-time control and analog conversion.

CM408 MBD Motion Control consists of two parts: EVM Oscar-Skylight Motion Control EVM (PMSM FOC control power backplane) and ADI M4 Control Card ( ADSP-CM408 control core board). The design fully takes into account the industrial isolation requirements and has complete isolation. CAN, RS-485, RS-232, Ethernet communication interfaces and complete isolation of the control part and high-voltage power part.

The software part adopts MBD (Model-based design), uses Matlab & Simulink tools to model motor control, and automatically generates the core code of the control part, which can greatly accelerate the development process of servo motor control software and provide complete and reliable code. Engineers can be allowed to focus more on the algorithm itself rather than getting caught up in the complex process of coding and modifying the code in the early research and development stage to accelerate the process of product innovation and new technology development.
