In a simulation study, a process is imitated by using mathematical models as a quick way of studying and evaluating the process for further design and optimization purposes. Simulations are carried out by using mathematical models with required assumptions for system inputs to determine the outputs. Hence, simulation of a process is based on availability of a computational model. Mathematical m...

In this paper, the use of continuous mathematical models of an aircraft in an aircraft simulator is described. The models are of lower degree and less time-consuming for calculation. Computer implementation of the models capable to work faster and more accurately and efficiently is also described. The suggested approach allows to achieve the required precision at accelerated simulation speed us...

The Phase-Locked Loop (PLL) system is used extensively in modern electronic systems such as modems, mobile communications, satellite receivers and television systems. This work presents a method for modeling and simulation of second-order PLL in time domain to study transient behavior during frequency acquisition and tracking. Here we utilize a basic PLL system that consist a multiplier, used a...

Composing of multi-pole models and simulation of dynamic responses of a technical chain system is considered in the paper. Part 1 of the paper discusses difficulties arising in using existing simulation tools. A methodology is proposed that seems to be free of most of these disadvantages. Modeling of electro-hydraulic servovalve is considered as an example of chain system. An intelligent simula...

Mathematical simulation method can be adopted to check flight characteristic of UAV, also can be adopted to simulate hardware experiments of unmanned aerial vehicle (UAV), then related flight experiments can be performed. The simulation method can reduce the flight periods, cost and risk. UAV flight model research play an important role in simulation and modeling in initialize periods of the UA...

Although, Single-Sided Linear Induction Motor (SLIM) utilization has increased in railway applications due to their numerous advantages in comparison to Rotational Induction Motors (RIM), there are some sophistication in their mathematical models and electrical drive. This paper focuses on the problems of SLIM modeling, with assuming end-effect on the basis of Field Oriented Control (FOC) as a ...

The in-pipe robots are currently of significant interest, considering numerous recent publications on this subject. Such machines can use various locomotion principles: wheeled, tracked (caterpillar), walking (legged), screw-type, worm-type, snake-type, etc. In most cases, such equipped with an active drive system transmitting the torque from a motor shaft to corresponding mechanism (wheels, tr...
