Traditionally, most spacecrafts with high security requirement use hardware redundancy to improve the system-level performance. However, the data exchange process and the coordination of multiple agents are very difficult to realize. In this paper, a Byzantine fault-tolerant GNC (Guidance, Navigation and Control) system is proposed based on the time-triggered architecture (TTA). This improved GNC...
In this paper, in view of the actual measurement of the Hall Effect gear tooth sensor (Hall Effect GTSs), a measurement system is established. Through the study, a reasonable, appropriate mathematical model is proposed, including the signal phase drift and the duty cycle of speed measurement system's output signals. The experimental results show that, the mathematical model is very effective to determine...
Because the present university sports teaching lacks the concrete application of humanistic education teaching mode, so it put forward that the game theory is used in sports teaching in Colleges and Universities, by using the participants, behavior, information, strategy and so on, the basic concept of the game theory to design teaching methods, teaching contents and evaluation methods. Then turning...
Aiming at the phenomenon of premature convergence and later period oscillatory occurrences, an adaptive particle swarm optimization algorithm with the changes of the population diversity was proposed. In the algorithm, the adaptive exponent decreasing inertia weight and a dynamic adaptive changing threshold were proposed, the satisfied particle of threshold will be mutation by the average distance...
Combustion modeling is a very important method in designing internal combustion engine. In this paper, a multi-zone one with diagnostic and predictive functions is proposed for combustion in a gasoline engine. This model has been used to predict the performances and their changing with variable parameters such as ignition advance angle and coefficient of the residual exhaust gas respectively, in a...
This paper concerns with the output feedback control for the nondeterministic discrete event systems (DES) with probabilities known. The nondeterministic DES models are introduced by using the minimax algebra to formalize the treatment of time sequences, and by using usual algebra to introduce a Markovian structure that assigns transition probabilities to events. Based on this representation, the...
