在调整电机电流环 PID 参数时,需要知道电机的 Lq、Ld 参数, D轴和Q轴电流环由这两个参数计算出比较合适的 PID 参数,后续再根据电流波形进行微调,本文主要介绍如何使用 RT1180-EVK、FRDM-MC-LVPMSM 低压驱动板、FreeMaster 测量电机的极对数和 Ld、Lq 参数。 1. 硬件连接 RT1180-EVK 在连接 FRDM-MC-LVPMSM...
Cortex-M33 + Coretex M7 雙內核高性能 MCU, Cortex-M33 主頻高達 240MHz, Cortex-M7 主頻高達 800MHz , 擁有 1.5MB RAM, 支持外掛Flash,支持 XIP,與以往的RT 系列相比較,RT1180 最大亮點則是支持 EtherCAT ,同時集成了 SINC ADC ,非常適合用在工業上,本文先介紹 RT1180 EVK 上手體驗,為後續使用提供基礎...
RT1180-EVK PMSM 电机电流环调试过程 上篇文章(使用 RT1180-EVK 和 FreeMaster 测量电机参数)讲述了电机参数测量过程,本文讲述知道电机参数后如何测试和再调整电流环PID 参数过程,硬件连接和 FreeMaster 的通信连接不再重复叙述,保持 MCU 程序正常运行和 FreeMaster 通信正常。 更改控制方式: 需要将控制方式更改到正常...
在電腦設備管理器可以查看串口號。 打開FreeMaster,並打開 RT1180 SDK 目錄中的 FreeMaster 工程: \SDK_2_16_000_MIMXRT1180-EVK\middleware\motor_control\freemaster\ pmsm_float.pmpx 在FreeMaster 菜單欄 Tools ---> Connection Wizard 指南中選擇串口號後連接 MCU。 點擊綠色按鈕(圖中 1)連接成功後,在測試...
i'm in a mcu choosing phase on my project so i need to understand is nxp is good or not, i'm developing an application using imx RT1180 with EVK board and MCUXpresso 24.x as SDK. I need to use external SDRAM and not DTC because my evaluation code is too lar...
Describe the bug below case are error CONFIG_GPIO=n but there is still dependency on fgpio.h, as the the board.h take the fgpio.h as default. but for zephyr this file is not needed. and in evkmimxrt1180_flexspi_nor_config.h, we can see b...
