Article deals with the problem of simulation modeling of robust control system for nonlinear plants with the input signal saturation, functioning under a priori uncertainty conditions and in the presence of several statement delays. With the help of computational experiments, the quality of the control system operation under various initial conditions of the controlled plant is illustrated.
The design of wireless embedded systems needs their efficient and realistic simulation to verify that requirements are met. The reproduction of communication behavior is crucial to assess the performance of hardware and software components, e.g., dependability and energy consumption. This work presents and discusses different levels of abstraction for the simulation of the communication behavior....
In classical virus spread model, the virus spreading process is described by infected probability, this process ignored some spreading details and the duration of contact. For this reason, we proposed a delay included dynamic virus spreading model and simulated the viruses' spreading process by cellular automata method. The unexpected result shows that the individual's moving behavior can hinder the...
Nowadays, many airports' capacity almost reaches its limitation; some airports begin to build new runway systems to satisfy the demand for air transportation. Choose which operational mode of the new runway system becomes a very tough question. This paper presents closely spaced parallel runway (CSPR) simulation using SIMMOD Plus. Thus, the method can advise the airport managers and air traffic controllers...
Dependability is becoming a key design aspect of today networked embedded systems (NES's) due to their increasing application to safety-critical tasks. Dependability evaluation must be based on modelling and simulation of faulty application behaviors, which must be related to faulty NES behaviors under actual defects. However, NES's behave differently from traditional embedded systems when testing...
In networked control systems (NCS) network-induced delays affect the performance of system and even cause instability. A discrete model of NCS was established in this paper, and a feedback control method based on forecast for State compensation was given in view of the model. The method was applied in a simulation model of inverted pendulum, and was confirmed to be effective .Finally, the paper points...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
