摘要
针对舵机系统自动控制的精度低,响应速度低的问题,提出了一种基于FPGA的逐点比较插补算法的数字系统设计方案,通过采用具有可综合,灵活度高,可并行执行等特点的Verilog HDL语言,再加上内部具有丰富逻辑资源的FPGA,从而快速精准地实现舵机控制。通过Quartus和Modelsim进行电路的综合以及系统的仿真验证了逐点比较插补算法的正确性,最终完成了对整体系统的实现,该设计可以应用和推广于图像识别自动跟踪领域。
Aiming at the problem of low precision and low response speed of automatic control of steering gear system,a digital system design scheme based on point-by-point comparison interpolation algorithm of FPGA is presented.By using Verilog HDL language with the characteristics of synthesizability,flexibility and parallel execution,together with the internal FPGA with rich logic resources,the steering gear control can be realized quickly and accurately.The correctness of point-by-point comparison interpolation algorithm is verified by circuit synthesis and system simulation of Quartus and Modelsim.Finally,the implementation of the whole system is completed.The design can be applied and extended to the field of automatic image recognition and tracking.
