  • Patent number: 8861553
    Abstract: 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.

  • Patent number: 8090455
    Abstract: 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.

  • Patent number: 7991590
    Abstract: An adaptive real-time analysis method for dynamic signals generated by rotary machines improves Vold-Kalman filtering order tracing technology to renew the algorithm logic so that on-line computation ability is achieved. Through signal simulation and practical engineering application to verify the availability, it shows that the output results are extremely accurate. As such, this method is advantaged to estimate the time-domain waveform of specific order signals for the operation of the rotary machines and to interpret the related physical phenomena. Moreover, this method can be applied for a digital signal processor (DSP) to obtain real-time and on-line computation of the order signals needed to be traced and to display the tracing time-domain waveform instantly.
