In recent years, a Digital Signal Processor (DSP) or Microcontroller has been widely used for implementing the digital motor control algorithm in the motor drive industry. Application spans widely from a low performance appliance AC inverter drive to a high performance servo drive. Today’s digital AC drive consists of the implementation of torque control by means of regulating the motor current...

The main task of paper studied new ciphering and deciphering techniques reported previously. Computer programs are designed in C language to perform theses algorithms and to assess their performance. Out of these algorithms, it is found that the BLOWFISH is the more sophisticated one. Therefore, a development for this algorithm is introduced to enhance its operation. This has been carried out b...

Abstract. Active Vibration Control (AVC) problem is successfully studied considering all the characteristics of a control problem. The controlled system consists honeycomb panel carbon fiber. Expensive devices are in general used for setting up and designing AVC this due to limitations practical implementation. In our work we point low cost solution using microcontroller that has been verified....
