Description: A typical example of using the dSPACE system for
electrical drives simulations is described in [9] and for wind
energy conversion systems (WECS) in [10].
However, before the real-time implementation, the
Control part has to be validated by simulation using a plant
model. This model could be developed using either the
Simulink transfer functions or the PLECS toolbox. Platform: |

Description: The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block. The motor drives a mechanical load characterized by inertia J, friction coeficient B, and load torque TL . The speed control loop uses a proportional-integral controller to produce the quadrature-axis current reference iq* which controls the motor torque. The motor flux is controlled by the direct-axis current reference id*. Block DQ-ABC is used to convert id* and iq* into current references ia*, ib*, and ic* for the current regulator. Current and Voltage Measurement blocks provide signals for visualization purpose. Motor current, speed, and torque signals are available at the output of the Asynchronous Machine block.-The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block.

Description: Variable speed drives with Pulse Width Modulation are increasingly applied in many new industrial
applications for more efficient performance. Recently, developments in power electronics and semiconductor
technology have lead to widespread use of power electronic converters in the power electronic systems. A number of
Pulse width modulation (PWM) schemes are used to obtain variable voltage and frequency supply from a three-phase
voltage source inverter. Among the different PWM techniques proposed for voltage fed inverters, the sinusoidal PWM
technique has been popularly accepted. But there is an increasing trend of using space vector PWM (SVPWM) because
of their easier digital realization, reduced harmonics, reduced switching losses and better dc bus utilization. This paper
focuses on step by step development of SVPWM implemented on a PMBLDC motor. Simulation results are obtained
using MATLAB/Simulink environment for effectiveness of the stud Platform: |
