Safety and efficiency of carrier flight deck are two important factors that have great effects on the comprehensive performance of carrier. This paper studies on path planning algorithms for carrier aircraft on the deck in consideration of safety and efficiency requirements. Firstly, a kinematic model of the carrier aircraft, obstacle avoidance models and boundary constraints are proposed. Subsequently,...
A global-crowding-distance based multi-objective particle swarm optimization (GCDMOPSO) algorithm is proposed in this paper. The concept of global crowding distance is introduced into the proposed algorithm to estimate the density of the non-dominated solutions in the external archive, and a dynamic global-crowding-distance based maintenance scheme is used to prune the external archive. Meanwhile,...
This paper presents a zoning positioning model based on minimize RFID reader. Compared with conventional RFID reader, the transmission power does not need to be fixed and it is not necessary to detect RSSI of tag. Compared with the landmarc algorithm and its improved Vire algorithm, the complexity of the equipment is simplified and the time is reduced during the positioning process. Minimize RFID...
The differential constant modulus (DCMA) multiuser detection can obtain higher steady-state decorrelating performance than the conventional linear algorithm under high SNR condition similar as the constant modulus algorithm (CMA). Unlike CMA criterion, DCMA has single global minimum which leads to the convergence independent from the amplitudes of received signal. However, the closed-form analysis...
As an important part of requirement management, managing requirement change plays a key role in controlling project schedule and costs at early stage. Effective requirement impact analysis would give proper assessment on the effect of certain requirement changes on the whole system, and provide useful information for making trade-off decisions on future system design and implementation. In this paper...
Dynamic matrix control algorithm is a predictive control algorithm based on step response of the object, suitable for complex control systems and the process whose mathematical model is difficult to be established precisely. In the article, the dynamic matrix control algorithm has been studied, we analyse the impact on system control quality using dynamic matrix control algorithms with different setting...
With the applications of predictive control in the process control, the research of algorithm and theory about the predictive control has also achieved great development. Dynamic Matrix Control (DMC) algorithm is a prediction-control algorithm based on the objectpsilas step response. It is suitable for the control systems which are complicate and difficult to build accurate mathematical models. This...
