The control model in the course of an aircraft auto-landing is first proposed. Then, the common basic hypotheses in the design of a fuzzy logic controller are described. The fuzzy inference system of an aircraft auto-landing fuzzy controller in the course of automatic control on landing is investigated. The auto-landing model for controlling, membership functions of state variables, inference rules in the system, algorithms for fuzzy inference and defuzzification, etc, are analyzed and devised in detail with the emphasis on optimal analysis and design of Takagi-Sugeno ALFC based on adaptive neural fuzzy inference systems. Finally, the simulation for verification and analysis of the designed schemes is made by utilizing Simulink and fuzzy logic toolbox with MATLAB. The simulated results show that the ANFIS based T-S type ALFC scheme has excellent behavior in performance.

This paper presents the method for the signal parameters selection to improve the processing gain (PG) of the single-user TH ultra-wideband (UWB) systems. The signal parameters provided by this method are independent of TH codes. First, the UWB system models are introduced. The UWB system operates in the multipath channel with NBI, and employs binary pulse amplitude modulation. Next, the processing gain is derived. Then, the method is given. At last, the effectiveness of this method is illustrated by an example.

In this paper we propose a service-oriented processmodel and a web service framework for collaborativeproduct commerce (CPC). The framework, calledMIDAS, integrates design process, business plan andassembly operations using the web services. A CPCprocess involves a collaborative process, which consistsof interdependent tasks. In a global environment, manytasks are outsourced to other companies. In MIDAS, atask is regarded as a service that an organization canprovide. The service discovery of MIDAS, throughUDDI, enables companies to find the services andprocesses other companies provide. MIDAS providesservice composition to support a process which involvesseveral services of other companies. MIDAS interface iswritten in XML and Web Service Description Language(WSDL), which facilitates platform independent processmanagement among heterogeneous and collaborativesystems.

The interaction balance method (IBM) with fuzzy constraints is proposed for large-scale industrial processes under hierarchical steady-state optimization with the consideration of the model-reality difference and the constraints of subprocesses being flexible. In this approach, the models that are treated as equality constraints and the inequality constraints of the subprocesses are all fuzzified. Two cases of interaction balance method are studied: the open-loop IBM and the IBM with global feedback. Simulation results show that the solutions of the proposed method with global feedback are very close to the optimal solutions of the real process.

In order to solve the hybrid and dependent task scheduling and critical source allocation problems, a task scheduling algorithm has been developed by first presenting the tasks, and then describing the hybrid and dependent scheduling algorithm and deriving the predictable schedulability condition. The performance of this agorithm was evaluated through simulation, and it is concluded from the evaluation results that the hybrid task scheduling subalgorithm based on the comparison factor can be used to solve the problem of aperiodic task being blocked by periodic task in the traditional operating system for a very long time, which results in poor scheduling predictability; and the resource allocation subalgorithm based on schedulability analysis can be used to solve the problems of critical section conflict, ceiling blocking and priority inversion; and the scheduling algorithm is nearest optimal when the abortable critical section is 0.6.
