An asynchronous master-slave serial communication system, a data transmission method, and a control module using the same are disclosed. The asynchronous master-slave serial communication system comprises a master control module and a slave control module. The master control module generates a check code according to an address information and a data information, and generates a data package according to the address information, the data information, the check code and the master clock signal. The slave control module generates a decoding data according to the data package and a slave clock signal, and generates the address information, the data information and the check code according to the decoding data.

Asynchronous master-slave serial communication system, data transmission method, and control module using the same thereof

A motion control servo loop apparatus, comprising: a feed-forward control module, and a proportional-integral-derivative (PID) control loop and a compensation adder. The feed-forward control module is capable of generating a feed-forward compensation. The PID control loop further comprises: a proportional control module, an integral control module and a derivative control module. The proportional control module is capable of generating a proportional compensation. The derivative control module is capable of generating a derivative compensation. The integral control module uses a digital differential analyzer (DDA) algorithm to perform integration for accumulated errors with respect to each sampling clock at each DDA pulse and thus output an accumulated error, which is then processed to generate an integral compensation. Thereafter, the compensation adder receives the feed-forward compensation, the proportional compensation, the integral compensation and the derivative compensation to calculate a position error compensation for a motor driver.
