Study on Rotating Speed Control System with Phase Locked Loop for Motor
DI Jing, ZHANG Shen, FAN Ti-feng
2002, 28(1): 12-14.
<Abstract>(17)
Abstract:
A control method of DC motor using phase locked loop (PLL) was analyzed. The combination model of DC motor and optic coupler was given. According the model, a PLL structure for DC motor control system was designed and the characteristic of the system was measured. A linear control characteristic at the range of 50～2400Hz was obtained.

<Abstract>(26)
Abstract:
Through distilling the characteristics of foam image, this paper studied the mathematical model of the ash and density of foam of flotation coal, classified foam image by their structure, established a flotation control system on LVQ nerve network model of recognition of foam framework.
Study on the Reliability of Fault-tolerant Control System
LIU Jun-yao
2002, 28(1): 17-18.
<Abstract>(26)
Abstract:
The intension of concept of reliability and the definition of reliability are discussed according to whether the fault tolerant control system satisfies performance requirement. The fault probability, the degree of fault tolerance and problem of reliabilty in the fault tolerant control system are analyzed in the view of statistics. And Markov chain is used to analyze and model for the reliability problem.
