异步电机软起动仿真5.16
说明： 异步电机作为电网中较为主要的负荷，对其的控制一直是重要问题。在异步电机的起动过程中，若直接起动，则会引起较大的电流，会影响电网的稳定和安全；且起动转矩和运行效率也较低。为改善上述问题，使用软起动器对异步电机进行起动，可实现启动电压的无极调节，从而限制启动电流，可在一定程度上改善电机性能。本文采用电流闭环作为控制方式，并采用MATLAB对异步电机软起动系统进行模型搭建和仿真，进而说明了软起动的优势。(As the main load in the power network, the control of asynchronous motor is always an important problem.In the starting process of asynchronous motor, if directly started, it will cause a large current, will affect the stability and safety of the power grid;The starting torque and operating efficiency are also low.In order to improve the above problems, the use of soft starter to start the asynchronous motor can realize the non-pole adjustment of starting voltage, thus limiting the starting current, which can improve the motor performance to a certain extent.In this paper, the current closed-loop is adopted as the control mode, and MATLAB is used to build the model and simulate the soft starting system of asynchronous motor, and then the advantages of soft starting are illustrated.)

CH11-KEA128-SPI
说明： 1. 硬件接线
（1）调试串口(UART_Debug)使用UART2，在“printf.h”文件中宏定义， 对应引脚为TX-PTD7，RX-PTD6
（在“uart.h文件中宏定义）。
（2）灯0~3（LIGHT_0~LIGHT_3）对应的引脚是PTC0~PTC3，高电平点亮（由硬件接法决定）
（3）SPI0_CLK对应的引脚是PTE0， SPI0_MOSI对应的引脚是PTE1，
SPI0_MISO对应的引脚是PTE2，SPI0_PCS对应的引脚是PTE3，
SPI1_CLK对应的引脚是PTG4， SPI1_MOSI对应的引脚是PTG5，
SPI1_MISO对应的引脚是PTG6，SPI1_PCS对应的引脚是PTG7。
（4）SPI0作为master,SPI1作为slave，SPI1接收SPI0发送的数据并产生中断。
用导线将PTE0与PTG4对接，将PTE1与PTG5对接，将PTE2与PTG6对接，将PTE3与PTG7对接。(1. Hardware wiring
(1) Debugging Serial Port (UART_Debug) uses UART2, macro-defined in "printf.h" file, corresponding pins are TX-PTD7, RX-PTD6.
(macro definition in the uart.h file).
(2) The pins corresponding to the lamp 0~3 (LIGHT_0~LIGHT_3) are PTC0~PTC3, and the high-level lighting is determined by the hardware connection.
(3) The pin corresponding to SPI0_CLK is PTE0, and the pin corresponding to SPI0_MOSI is PTE1.
The pin corresponding to SPI0_MISO is PTE2, and the pin corresponding to SPI0_PCS is PTE3.
The pin corresponding to SPI1_CLK is PTG4, and the pin corresponding to SPI1_MOSI is PTG5.
The pin corresponding to SPI1_MISO is PTG6, and the pin corresponding to SPI1_PCS is PTG7.
(4) SPI0 acts as master and SPI1 acts as slave. SPI1 receives data sent by SPI0 and generates interruption.
PTE0 and PTG4 are docked by wire, PTE1 and PTG5 are docked, PTE2 and PTG6 are docked, PTE3 and PTG7 are docked.)
