Abstract

This project presents the Design and Implementation of Access control System using PIC Microcontroller. The design is coded and implemented using MikroC language for the purpose of implementation inside the PIC Microcontroller. This design consists of a remote sensor which is used to detect the feedback signal. Automatic door system is used as an industrial application for the access control system where presented by this paper. The automatic door system model is designed and implemented with PIC-16F877A micro controller, laser sensor and DC motor and custom designed structure for its automatic door system. MikroC programmer is used to test the design codes, and Protus Simulation program is used for the purpose of simulation for the schematic of the design. The design needs maximum clock frequency of 4 MHz. Therefore, the proposed design will be able to cover a wide range of applications with a high sampling rate. Enhancements are made for the design to decrees the memory size in order to get fast execution time. The used ROM is 600 Byte (7.3%) from 8191 Byte and the used RAM is 93 Byte (26%) from 368 Byte of the memory size of PIC Microcontroller. Experimental results show a fast execution time for detecting the interrupts of the remote sensor. Therefore, the proposed Access Control System can be used with different industrial applications. It is very convenient system for consumers and has extensible and flexible characteristics. It can also be used for home doors with additional sensor devices.

Abstract

This paper presents a newly developed method with new algorithms to find the numerical solution of nth-order state-space equations (SSE) of linear continuous-time control system by using block method. The algorithms have been written in Matlab language. The state-space equation is the modern representation to the analysis of continuous-time system. It was treated numerically to the single-input-single-output (SISO) systems as well as multiple-input-multiple-output (MIMO) systems by using fourth-order-six-steps block method. We show that it is possible to find the output values of the state-space method using block method. Comparison between the numerical and exact results has been given for some numerical examples for solving different types of state-space equations using block method for conciliated the accuracy of the results of this method.

Abstract

This paper presents a fuzzy logic controller for a two-tank level control system, which is a process with a dead time. The fuzzy controller is a proportional-integral (PI-like) fuzzy controller which is suitable for steady state behavior of the system. Transient behavior of the system was improved without the need for a derivative action by suitable change in the rule base of the controller. Simulation results showed the step response of the two-tank level control system when this controller was used to control this plant and the effect of the dead time on the response of the system.

Abstract

The information is to used for system identification which involves the determination of model structure, parameter estimation and also signal estimation of non-measurable signals such as noise signals in stochastic systems. The determination of the model structure requires a construction of a mathematical representation of the system relevant to the problem at hand. Identification is classified into parametric and non parametric procedures. Parametric identification is used to identify the system parameters. On the other hand, non parametric identification method is used to map the input-output properties of the system. In this work different types of neural networks architectures, namely, feed forward neural network and Hopfield network are used as parametric identifier for both continuous and discrete control systems with different orders and types assisted by an off-line computer simulation using C++ language. Hopfield Neural Network is used as a parametric identifier with assumption of the availability of system states for measurement then, identification is performed based on input-output measurement only. Simulation results show the capability of these types of NNs to identify the unknown parameters of the plants.

Abstract

Engineering structures in general require at implementation conducting engineering surveys of the implementation stages of work to keep up with identical implementation of the technical specifications, on the other hand most of the facilities task (large structures, towers, dams, bridges, etc…) require the conducting of periodic monitoring to determine any change could happen with time in the three-dimension( X,Y,Z).The traditional approach in this proposal for this business is by conducting a field survey using ground surveying devices in addition to the photogrammetry survey, regardless of the manner of the work requires the provision of a number of well distributed ground control points for the purpose of the above required survey work.This research includes the application of(CTSS)system for a structural survey above as well as monitoring facilities disregarding the control points to provide cost, time and effort. The results using this technique(CTSS)are very promising (RMS in X= ±1.7 mm, Y= ±1.7 mm, Z= ±0.9 mm).which gives an overall precision of (RMS= ±2.6 mm).

Abstract

The system proposed in this paper design a system of intelligent reservoir " water level sensor" helps reduce thewaste percentage of water. Through the automatic control and control of the water level by determining the water proportion of the reservoir in terms of emptiness and fullness and is carried out using the concept of artificial intelligence with micro controls, where the use of a simple and cheap control is arduino and is stored and stored information is written in IDL program to determine the percentage of fullness and lack Depending on the need of the user of the reservoir with the management of electronic parts associated with the Arduino to fill the tank when it is free of water and stop the filling process when reaching the specified level of fullness while monitoring the level of water during use. This system can be applied at the level of tanks reservoirs Cities and irrigation tanks and reservoirs for agricultural land with the development of electronic parts used in the control system to achieve the desired goal in preserving the amount of safe water for drinking and non-potable.
