| 在双电机同步控制中，需要传递电机的关键控制参数来保持其同步运行，利用普通的通信总线进行信息传递会有延时，影响同步精度。为了实现双电机高精度同步控制，课题组提出基于双内核的TMS320F28379D芯片来实现双电机同步控制的方法。首先，设计了双内核CPU的IPC通信，避免信息交换的延时；然后，利用芯片的SDFM模块完成电流检测，简化了电流检测电路；最后，针对电机运行的不同场景，提出了不同的控制策略。通过实验证明该方法可以实现2台伺服电机的同步控制，并可预见的是利用该芯片可实现多至4台电机的同步运行。 |

| In dual motor synchronous system, it is necessary to transfer the key control parameters to keep its synchronous operation. However, using the common communication bus to transmit information will cause transmission delay, which will affect the synchronization precision. In order to realize the high precision synchronous control of dual motors, a method to realize the synchronous control of dual motors based on TMS320F28379D chip with dual CPUs was presented. Firstly, the IPC communication of dual CPUs was designed to avoid the delay of information exchange. Then, the current detection circuit was simplified by using SDFM module of the chip. Finally, different control strategies were proposed for different scenarios of motor operation. Experiments show that this method can realize synchronous control of two servo motors. And it is foreseeable that the chip can be used to achieve up to 4 motor synchronous operation. |
