Many control schemes have been proposed for induction motor and permanent magnet synchronous motor control, which are almost highly complex and non-linear. Also, a simple and efficient method for unified control of the electric moto are rarely investigated. In this paper, a novel control method based on rotor flux orientation is proposed. The novelties of proposed method are elimination of q-ax...

Background: Children with autism should interact and get along with their surrounding environment. Therefore, the researchers must try to explain the reasons of challenges in their adaptive behaviors. This study aimed to evaluate levels of challenges in sensory processing and the motor domain of adaptive behavior among children with autism in Egypt, and to explore the effect of sensory processi...
