Since the 1970s, the number of industrial robots in China has been relatively large, and some of the technologies of robots have reached the world's advanced level. However, industrial robot technology in western developed countries still leads China for many years. . The reason is not difficult to find: the method adopted by China to study industrial robots is mainly to introduce foreign advanced technology and then carry out secondary development. This has caused China's own innovative technology to be less, which seriously restricts China's industrial robot industry. Development.
In order to break the foreign technology monopoly of industrial robots in China, we must be self-reliant, master the key technologies of high-performance industrial robots, and innovate on the basis of the original. Since the actuator of the industrial robot joint is a motor, it is very important to obtain a good control effect of the motor. In order to obtain excellent motor control performance, a high-performance AC servo drive system is required, so a high-performance AC servo drive system is developed. It is one of the key technologies of industrial robots.
The hardware of the AC servo drive system is the basis of software design, so the main task of this paper is to design the hardware of the system according to the characteristics of the industrial robot servo drive system.

1.1 DSP selection
DSP system hardware design includes control chip selection, main circuit drive and protection, peripheral equipment, logic circuit, etc. It is the basis of the entire control system design, DSP chip is the top priority. TMS320C5000 series DSP has the lowest power consumption and is designed for the consumer digital market. The minimum power consumption is only 0.33mA/MHz, so it is mostly used in daily life consumer products such as cameras and mobile phones. TI's TMS320C6000 series has the highest processing power and is a digital processor suitable for programming in high-level languages ​​such as C++/C. It is mainly used in high-end fields such as military defense. Compared with the C5000 and C6000 series of DSPs, the TMS320C2000 series of DSPs are the most powerful processors in the control field due to their fast speed, high precision and high integration. Among them, C28 series DSP is a new member of TMS320C2000 platform. It is improved by C24 series DSP. It is a chip that supports C/C++ language design. C28 series DSP is very suitable for industrial control and has unique control in algorithm control. The advantage is a rare microprocessor that is efficient enough to replace any other processor. C2000 series DSP does not contain Flash memory, only contains read-only memory ROM; F2000 series DSP not only contains ROM read-only memory, but also includes Flash memory, which can be repeatedly erased and written, suitable for application in the initial development stage of the product. If the TMS320C281x is used, the code needs to be delivered to the manufacturer, and the program is solidified into the ROM of the TMS320C281x, which increases the cost, so the TMS320F281xDSP chip is selected. Among them, TMS320F2812 as TI's first chip, has a high cost performance. In summary, the final selection of the DSP model is TMS320F2812.
