In this paper, a general missile modeling is presented. An accurate model for missiles is proposed taking into consideration the rigid body dynamics in 3D space with 6 degrees of freedom. Different coordinate systems, variation of missile mass, aerodynamics, air speed and density, gravity, propulsion system, actuators, measurement and tracking devices are(More)
This paper presents the approach of the translation from timed automata into B-method. We are modeling using a network of timed automata, extended with data types, which is the modeling language used for UPPAAL tool and convert this model into B-method system. The integration of UPPAAL and B-method gives the advantages of both tools; the UPPAAL modeling(More)
In this paper, a dynamic model of the magnet levitation nonlinear process is identified as a neural network. The accuracy of the model is tested and verified even if the observed input/output data contains noisy components. Three layers neural network controller is proposed and developed in order to track the set point and regulate against disturbance. The(More)
A control scheme (GFPID) is proposed to control processes that have varying parameters. These processes are very common in nature. Usually, traditional controllers are not suitable for these processes. The new control scheme combines the traditional PID controller with genetic algorithm and fuzzy logic to solve this problem. The optimum PID settings to(More)
S u m m a r y I T h e control of distributed parameter systems with constant, but unknown parameters is considered. A weighted average of the distributed output on the spatial domain is defined as a new variable and is used to generate the control. The parameters of the model are estimated using recursive least squares estimation. The control is obtained(More)
The fed-batch fermentation process is nonlinear and often operated at unsteady state. In this work, a supervisory control system was added to a fed-batch fermentation plant. The objective was to preserve the final biomass concentration, as nearly as possible to its ideal final value, even if the process input was subjected to changes. The main process input(More)
