Pulse frequency modulation control system 脉冲调频控制系统
The paper introduces the design of digital variable - frequency induction motor speed modulation control systems , based on fpga 本文提出了一种采用现场可编程门阵列( fpga )器件实现数字化变频调速控制系统的设计方案。
The thesis tries to solve the problems in two ways : carrier wave modulation control methods and deadbeat control methods as well as some theoretic problems discussed 本文从载波调制控制和无差拍控制两个方面进行了尝试,并对一些理论问题进行了一些探讨。
Furthermore , cpld design is the necessary step for the verification of asic design . in this paper , several cpld speed modulation control systems and ip are presented 本文设计的几种cpld调速控制系统以及几个ip核,一部分下载到芯片,通过实际验证;一部分通过仿真验证。
