In response to the industrial automation trend, in addition to the development of industrial equipment, the construction of the motor control network is also crucial, thus blowing up the trend of industrial motor networking. Compared to a microcontroller (MCU) or digital signal processor (DSP) solution, a field-programmable gate array (FPGA) system single-chip (SoC) with parallel computing advantages and the ability to expand multiple communication interfaces will be in this wave. The design trend takes advantage.
Xilin, Xilinx Asia-Pacific Zynq business development manager, said that white goods usually only need MCU as the core of motor control, but the control system center of high-end industrial motor adopts separate design to cope with complicated operation. Mechanism; if the DSP is responsible for the algorithm, the MCU is responsible for the human-machine interface control, and the FPGA is responsible for the high-speed input/output (I/O) communication interface.
Luo Lin further pointed out that "manufacturing intelligence" and "customization of production lines" have made more and more factory equipments interconnected with equipment and equipment, which also makes engineers prefer to use "distributed" networks to design industrial motor control systems; That is to say, the industrial motors must also have interconnection communication functions between each other. As a result, the monitoring data such as temperature, humidity, current, voltage, and fault diagnosis of the motor can be returned to the engineers through the cloud center to further complete the complete operation. Industrial automation vision.
The networking requirements of industrial motors also make the control center of the separate industrial design in the traditional industrial motor useless, and must be further realized by the FPGA SoC with higher performance and parallel computing function.
Luo Lin added that industrial motors have high acceptance of high efficiency and high cost permanent magnet synchronous motors (PMSM). Therefore, in addition to networking and communication control, high-performance inverter control design is also the focus of FPGA SoC. In view of this, Xilinx also introduced the Zynq-7000 AP SoC Intelligent Drives Platform, which is based on the Zynq-7000 FPGA SoC. In addition to providing support for power semiconductor components, the platform also focuses on field oriented control (FOC) algorithms. The layout of the industrial Ethernet protocol.
In addition, the concept of Model-based Design has been popular in Europe in the past, but with the heat of motor control issues, motor control developers in Asia have begun to accept this new design concept. Therefore, semiconductor component companies including Analog Devices (ADI) and Xilinx have begun to develop motor development tools based on their own solutions based on system modeling tools such as MathWorks. Luo Lin pointed out that MathWorks launched a new design method specifically for the Zynq-7000 FPGA SoC in March this year, which can shorten the industrial motor development time from several months to several weeks.
