文档介绍：摘要
在现代运动控制系统中,经常会碰到两台电机通过某种联系作用于同一工作机构的系统。由于同型号的两台电机也不可能能做到参数完全一致,因此两台电机在共同拖动同一负载的情况下,彼此的负载就不可能相同,由此容易造成其中的一台电机工作在轻载的状态,而另外一台电机工作于过载的状态下,出现过热,容易磨损等问题。为克服这种情况,达到负载的合理分配,就必须解决两台电机的功率平衡问题。
本论文针对上述问题,设计了一个鼠笼式双电机同轴驱动功率平衡控制系统,并进行了相关研究。文中首先对双电机功率平衡的机理和条件进行了阐述和分析,并进行仿真研究;针对双电机同轴驱动中的负载分配不均问题,提出了采用基于直接转矩控制的主从控制方案,主电机采用速度控制,从电机跟随主电机的转矩给定。

ABSTRACT
In the modern motion control system, two motors often run into the role of a link through the work of agencies in the same system. As a result of the same type of two motor parameters can not exactly drag the two shared the same electrical load, the load on each other can not be the same, which easily lead to a motor which in state of light load, while the electrical work in a state of overload, resulting in overheating, easy to wear. In order to e this situation, to achieve a reasonable distribution of the load, it is necessary to solve the two electric power balance.
     In this thesis, to these issues, we designed a double squirrel-cage motor drive coaxial control system of power balance and the related research. First, the electric power balance of the dual-mechanism and conditions of the description and analysis, and simulation studies, for double-motor-driven coaxial load uneven distribution problem, a direct torque control based on the master-slave control scheme the use of speed control of main motor, main motor from the motor torque to follow a given,.
