Design and Development of Computer Controlled Active Sonar System

چکیده
Original scientific paper Nowadays computerization is the most popular, reliable and flexible design for various types of control and communication systems. Sound navigation and ranging (SONAR) is a modern ultrasonic range finding technique used for collecting the information of a distant object without any physical contact. In this paper, a personal computer (PC) based active SONAR system is presented. The developed SONAR system contains both transmitter and receiver parts in the same module. A pair of 40 kHz piezoelectric ultrasonic transducers is used to transmit ultrasound toward the object and receive the reflected from the object respectively. A driver-software named CURF (Computerized Ultrasonic Range Finder) is developed for this system, using Turbo C language aimed at IBM PC and its clone machines. The CURF software provides necessary support for interfacing the developed hardware as well as desired calculations. A number of tests have been done and it is found that the performances of the developed system are good in terms of accuracy, simplicity, cost and power consumption.

Discrete Time Control Method for SVM Direct Active Power and Stator Flux Control of PMSG-Based Wind Turbine
This paper proposes a new method for direct control of active power and stator flux of permanent magnet synchronous generator (PMSG) used in the wind power generation system. Active power and stator flux are controlled by the proposed discrete time algorithm. Despite the commonly used vector control methods, there is no need for inner current control loops. To decrease the errors between refere...
