查询词典 stepping

Based on modeling and simulation of the steady characteristic of five-phase hybrid stepping motor driver system with fixed-chopping frequency, constant total current driving and new pentagon winding connection pattern, the paper studies the dynamic characteristic of the system, especially single step response characteristic.

本文在建立绕组接法采用新五边形接法，驱动方式采用恒频斩波恒总流驱动时的五相混合式步进电动机系统的稳态仿真模型的基础上，分析研究了其动态特性，并重点对单步响应特性进行了研究与分析。

What this paper finished mainly work as follows: Five-phase hybrid step motor driver system with fixed-chopping frequency and constant total current driving is fully described. Mathematical model of the system, included the current control circuit, power driving circuit and five-phase hybrid stepping motor is established. The steady modeling of the system is established and studied. Based on the steady modeling of the system, dynamic modeling of the system is studied and single step response characteristic is constructed with MATLAB/Simulink. The simulation results, which is certified by the theory analysis, coincide with the theory analysis.

本文主要完成的工作包括几个方面：对五相混合式步进电动机恒频斩波恒总流驱动系统进行了完整的描述；建立了包括电流控制电路、功率驱动电路以及五相混合式步进电动机在内的恒频斩波恒总流驱动系统的完整的数学模型；基于MATLAB/Simulink建立了恒频斩波恒总流驱动系统稳态仿真模型，并进行了仿真；在建立其稳态仿真模型的基础上，对动态模型进行研究，并借助于MATLAB/Simulink工具建立了恒频斩波恒总流驱动系统单步响应特性的仿真模型并对其单步响应特性进行了仿真研究，仿真结果与理论分析相符。
