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.

Backsteppnig control is applied to the positioning of ironless linear motor stage in this thesis. The controller design starts from a lower dimension subsystem and design a Lyapunov candidate for it. By choosing some appropriate virtual control input, the stability of the subsystem is guaranteed. Then extend to a larger system and choose a stabilizing control input for the extended Lyapunov candidate. The procedure is repeated until the overall system's actual control input appears, Again, the overall system's stability is guaranteed when the control input is appropriately chosen.

本论主要探讨逆向步进控制器在线性马达轨迹之控制，控制器之设计方式是由后往前一步一步推导，每一步推导的子系统，均满足Lyapunov稳定法则，在由后往前一步一步推导过程中，每往前推导一步，均必须符合最先所假设的条件与设计，直到方程式与系统的控制输入出现关连性，利用所设计之控制输入将系统的非线性问题予以解决，并因满足Lyapunov稳定法则而收敛。
