基于FPGA的异步电动机控制系统检测电路

摘要

According to the characteristics of flexible configuration and high-speed parallel processing capabilities of FPCA, the current and speed detection circuits for control systems of asynchronous motors were designed based on FPGA. The circuits have high real-time characteristic and strong adaptability, and can preferably solve the problem that the detection circuits using serial chip microcontrollers as control cores have lower real-time. The functional tests validate the feasibility of these circuits.%依据FPGA具有内部可灵活配置、高速并行处理能力强的特点,设计了基于FPGA的异步电动机控制系统中电流、转速检测电路,这些电路具有实时性高、适应性强等特点,较好地解决了单片机等串行控制芯片为核心的检测电路实时性不高的问题.通过功能实验验证了该设计方法的可行性.
