    ABSTRACT: In view of design characters of CCBII brake, a state monitor system based on multi-hierarchy evaluation architecture and fuzzy evaluation method is given. Block diagram of brake state monitor system is given, and design features and functions of each part are described, design methods of factor set, safety degree set and itpsilas criterion in multi-hierarchy evaluation system are discussed. Key points in multi-hierarchy fuzzy evaluation method are deduced essentially, such as diagnosis matrix based on weight set, subordinate degree matrix and multi-hierarchy fuzzy evaluation matrix based on weighted average model. Finally the whole CCBII Brake performance evaluation results are given. The application result shows that the system fits the design features of CCBII brake very well and is available for improve the operational efficiency in depot maintenance.

    ABSTRACT: For a certain real-time task scheduling problems with characteristics of uncertain task sets, the executing time dynamic changing and the task's mutual coupling strength dynamic changing, a multi-tasking dynamic scheduling algorithm is proposed based on dynamic weight value compensation and adaptive task jumping, which solved the loads storming caused by the dynamic task scheduling as well as the too long system response time caused by the changes of the tasks' coupling coefficient. The scheduling diagram and function of the modules are given firstly. Then, the focuses are the implementation of the execution controller and the weight compensation method based on the research of task weight value, the weight compensation and weight classification. The reliability and efficiency of the algorithm is verified by comparing tests, and has been applied to the combining heavy-duty train's braking condition monitoring and early warning system.

    ABSTRACT: To achieve braking control of locomotive brake control system (LBCS) accurately and steadily under high nonlinearity various time delay condition, a locomotive brake control method based on T-S fuzzy modeling predictive control (MPC) is proposed. Firstly, the paper uses fuzzy clustering method (FCM) to initial parameters, and uses back-propagation algorithm to rectify rectified its premise parameters by learning off-line. The consequent parameters of the fuzzy rules are self-learning online by recursive least square method with the forgetting factor. By introducing the conception of quality satisfying degree to rectify forgetting factor, the paper can
