A microprocessor as the core of the digital controller has become one of the major features AC speed regulation system in modern. Based on DSP as the core of the speed control system,it can realize complex algorithm. At the same time, it can achieve the diagnosis of system’s fault, and the self-setting of parameters controlled, etc. Thus it can make the motor speed control system have higher performance. This paper introduces the motor speed control system which consists of three DSP. This system is able to adjust two Frequency conversion motor. Division of work to the DSP is according to the function of DSP. Inter-DSP makes use of dual-port RAM to exchange data and communicate. They work together to achieve and improve the performance of the control system.

With the strengthening of interconnected power grid connection, interval oscillation mode damping continue to improve, interval power oscillation accidents still occur, however, the negative damping mechanism of the classic cannot be satisfactorily explain these phenomena, this paper provides the researches forced oscillation mechanism of the low frequency oscillation, the speed control system is likely to form the forced oscillation source, speed regulation system and low frequency oscillation formed an adverse coupling effect. In this paper, based on the mechanism of their method, speed control system are analyzed, the effect of various parameters on the low frequency oscillation in order to avoid speed regulation system to participate in the low frequency oscillation provides technical support.

The DC motor has good characteristics of large starting torque and good traction and strong overload capacity, traditional battery motor vehicle often adopts DC motor drives as driving system and uses the series resistance to adjust speed. However, in actual coal production, since motor vehicles are often placed in wet, explosive and dusty environment, the speed control system of motor vehicle has strict proof and moisture requirements, however, the inherent characteristics of the DC motor make it a serious shortcoming in the coal mine production, there is an urgent need to improve the structure to meet today's actual demand for coal mine automated production. This article is in this context, to compare the DC motor speed control system with AC speed control system of the mine car, discussing today's mainstream technical programs of AC speed control system, focus on the analysis of the great differences over performance and economic efficiency of the speed control system of mine motor vehicle after adopting AC speed control system.

A relatively low-cost personal-computer-based system is used to condition monitor a servo-valve-motor speed control system. Line pressures-flowrates together with motor torque-speed are monitored via 12 bit analogue to digital converters, and a set of performance characteristics are transformed into a mathematical model for the system in its run-in condition. Leakage flows are then introduced from each line, to simulate the onset of failure, and across the lines to simulate motor cross-port leakage deterioration. A graphics and software package is then developed and used to indicate which of the faults is occurring.
