Name of Equipment
ds1104 R&D Controller Board
Description
The most powerful controller, i.e. ds1104 R&D Controller board which is widely used in many university laboratories is utilized to obtain efficient and reliable control/drive systems. This controller board offers great features such as
- - Single-board system with real-time hardware and comprehensive I/O
- - Cost-effective
- - PCI hardware for use in PCs
- - User friendly, the control algorithm can be programmed using C-language or Simulink/Matlab
- - Powerful instruments to visualize and tuning the control parameters in real-time
These great features offer superior development system for rapid control prototyping (i.e. reduce the implementation time to minimum) and hence enhance research productiveness.
Name of Equipment
Supporting System
Description
The supporting system consists of i/o ds1104 terminals, level shifter and buffer circuits with FPGA as supporting controller board, gate drivers, power inverter, currents and speed measuring units. The supporting system is reliable and immune to noise/EMI. The CPLD/FPGA is utilized (optional) as a supporting processor/controller board to minimize computational burden of main ds1104 controller board. In addition, the use of FPGA provides extra switching PWM signals with blanking time which is mainly required in multilevel inverters.
