【摘要】 应用定点数计算在Handel-C语言中,实现了在Xilinx公司的现场可编程门阵列(FPGA)芯片上的直流伺服电机角度位置控制的比例微分(PI)控制器。PI控制器大约占用了FPGA virtex v1000整个容量的1%,其最大时钟频率为4.6 MHz。通过设计对现场可编程门阵列在数字控制应用软件中的性能做出了评估。实验和仿真表明,对于一些常规数字控制应用软件来说,现场可编程门阵列具有足够强大的计算能力。更多还原

【Abstract】 A Proportional-Integrate controller was implemented on a single-chip Xilinx Field Programmable Gate Arrays(FPGA).The controller was designed for angular position control of a DC servomotor.The FPGA was designed in Handel-C language,using Fixed-point numbers.The PI controller took approximately 1% of the total look-up-tables of a Xilinx virtex v1000 FPGA,and had a maximum clock rate of 4.6MHz.The goal of this work is to evaluate the FPGAs’performance in digital control applications.It was concluded that FPGAs have sufficient computation power for some custom digital control applications.更多还原
