dSPACE在逻辑无环流可逆调速系统中的应用

The Application of dSPACE to Logic Non-Loop-Current Reversible DC Speed-Regulating System

逻辑无环流可逆直流调速系统模拟实验线路复杂,且参数调整困难。本文将dSPACE引入到逻辑无环流调速系统中,在Simulink下搭建速度控制器ASR、电流控制器ACR和RTI接口模块,逻辑控制环节DLC的输出端控制正桥和反桥晶闸管的导通与关断。实验结果表明,该设计线路简单,参数调节方便,且适合将一些先进控制算法用于逻辑无环流系统中。

The simulation experiment circuit of the logic non-loop-current reversible DC speed-regulating system is complex and the parameter adjustment is difficult. In this paper dSPACE is introduced to the logic non-loop-current system. A model composed of speed controller,current controller and RTI interface module is set up in Simulink. The output of DLC is chosen to be the strobe signal of bridge and anti bridge. The experimental results show that the circuit of the design is simple. It has convenient parameter adjustment,and some of the advanced control algo-rithm for logic non-loop-current system.
