Flux switching permanent magnet synchronous motor (FMSM) has the characteristics such as large output torque, fast speed response and high reliability, so it can be widely used in the field of high-performance and high precision control.In the permanent magnet synchronous motor control system, the speed loop usually adopts the PI control algorithm. Although the PI control algorithm is relativel...
Objectives: The present study examined the effect of home-based handling training of mothers on the improvement of gross motor function of children with Cerebral Palsy (CP). Methods: In this randomized control trial, 42 children with CP (5-12 years old) were randomly assigned into the intervention and control groups. Data were collected using the Gross Motor Function Classification System and ...
Introduction The purpose of the present study was to assess the effect of motor imagery training after exercise on motor memory consolidation in the elderly. Materials and Methods The statistical population of the study consisted of healthy men and women in Mashhad nursing homes 22 persons were randomly assigned to 2 groups: motor imagery and control (each group included 11 participants). Int...
In the structure of direct vector control of an induction motor, there are three main sections that have important role in improvement of the induction motor drive operation. This three sections, including: 1- the estimation block of the feedback signals, 2- the block of the required PWM pulses generation for the inverter unit, and 3- control blocks (usually PI) for generating the require...
In this paper a sliding mode controller (SMC) is designed for a permanent magnet direct current (PMDC) motor to enhance the motor performance in the presence of unwanted uncertainties. Both the electrical and mechanical signals are used as the inputs to the SMC. The complete motor control system is simulated on a personal computer with different design parameters and desirable system performanc...
Objectives: Motor therapy plays a key role on the bilateral coordination skills and motor activities of children with Intellectual Disability (ID). The present research aimed to investigate the effectiveness of motor therapy on motor skills and bilateral coordination skills of students with ID. Methods: This was a quasi-experimental research with pre-test and post-test and control group desig...
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...
the aim of this study was to examine the effect of a rhythmic motor program on the perceptual – motor abilities (pma) and the intelligence quotient (iq) of educable mentally retarded (emr) children. the sample consisted of 24 emr girls (mean age = 11.98+1.43 years and iq = 70.58+ 9.95). then, they were matched and assigned to two groups of intervention and control according to their iq and pma ...
