Continuous correction of train absolute position in local area is accomplished by connecting distance detect sensor group to on-board Automatic Train Protection (ATP) system and installing the height difference positioning matrix on the wayside. The on-board ATP system can detect every unit height of the height difference positioning matrix row element, and transfer the heights into a unique position...
Based on the development and application of on-board subsystem test bench for current CTCS-3 system, this paper focuses on the approach of automatically generation of test sequence, takes the existing test sequences of ETCS-2 (European Train Control system level 2) as the train set existing relatively mature test sequence as the training set, to execute association rule mining. The whole data mining...
In this paper, an effective adaptive control approach is constructed to stabilize a class of nonlinear discrete-time systems, which contain unknown functions, unknown dead-zone input, and unknown control direction. Different from linear dead zone, the dead zone, in this paper, is a kind of nonlinear dead zone. To overcome the noncausal problem, which leads to the control scheme infeasible, the systems...
Voice coil motor (VCM) is one of the linear electric machine which has faster transient response, higher accuracy. It is widely used in the field of high performance direct drive servo valve. The mathematic model of voice coil motor was analyzed and the position control system of direct driver valve that based on voice coil motor was designed. Against the disturbance in the system, a new position...
The simulative modules of speed regulating system of BLDCM were built based on the mathematical model. The transfer function of the rotating speed was obtained. The fuzzy PID parameters of self-adaptive controller were introduced. The function of PID controller was improved according to both the error and the variety rate. The simulative results show that self-adaptive Fuzzy-PID Control has faster...
