Abstract: |
A novel, simple and reliable
digital firing scheme has been implemented for soft starting and speed
control of three-phase induction motor using ac voltage controller. The
system consists of three-phase supply connected to the three-phase induction
motor via three triacs and its control circuit. The ac voltage controller has
three modes of operation depending on the shape of supply current. The
performance of the induction motor differs in each mode where the speed is
directly proportional with firing angle in two modes and inversely in the
third one. So, the control system has to detect the current mode of operation
to choose the correct order for the firing angle of triacs. Three sensors are
used to feed the line currents to control system to detect the mode of
operation. The control strategy is implemented using a low cost Xilinx
Spartan-3E field programmable gate array (FPGA) device. Three PI-controllers
are designed on the FPGA to control the system for the three-modes. Simulation
of the system is carried out using PSIM computer program. The simulation
results show stable operation for different loading conditions especially in
mode 2/3. The simulation results have been compared with the experimental
results from laboratory prototype. |
