| Abstract |
The paper deals with the reconfiguration computing method applied for the vector control system of the asynchronous motor supplied from the failed and non-failed tandem frequency converter. The tandem converter has a hybrid topology consisting of two parallel-connected DC-link converters of different type and different power. It is containing a pulse-amplitude-modulated Current-Source Inverter (CSI) of large power and another pulse-width-modulated Voltage-Source Inverter (VSI) of reduced power. The proposed synchronization ensures the proper distribution of motor currents between the two component inverters. The tandem-converter-fed drive is also able to operate if the VSI is out of order, but the control strategy needs modification. In both cases the vector control structure is oriented according to the resultant rotor flux. A modular structure of the control systems allows the easy changing and rapid prototyping of the schemes. The control blocks for the described drive systems are implemented using Xilinx configurable logic cells (FPGA) and they are parts of a module library. The created library modules were compared with the corresponding Simulink modules. The comparison was made from point of view of the simulation. The module library quantisation errors were also studied for each implemented module. MATLAB-Simulink simulations are presented of the whole drive system concerning the reconfiguration of the control structure from tandem-converter-fed asynchronous motor to the CSI-fed one. |
