| 摘 要： | 测算股权制衡度时不考虑股东间的关联关系可能引致偏差。鉴此，重新测算了股权制衡度，以2003~2013年927家A股主板上市公司为样本研究其与公司绩效的关系。结果表明：“新股权制衡度”与公司绩效为非线性的U型关系，而“旧股权制衡度”与公司绩效为线性关系；［1,2］为股权制衡度对公司绩效影响的灰色区间；股权制衡度与公司绩效的关系受股东持股模式和外部环境影响。研究结果支持条件有效论，适度的股权制衡才能发挥积极作用。

| Abstract: | This paper studied the coaxial dual-motor load power tracking. In this system, the speeds of two synchronous motor were forced. Due to the slight parameter difference in the two identical motor, it will lead to uneven power distribution. According to the vector control theory, the AC motor torque and motor flux of the induction motor were decoupled. The mathematical model of dual-motor power (current)-tracking was controlled by fuzzy controller design and iterative algorithm to solve the power to track all issues. Simulation results show that the fuzzy PID control system, compared with the control iterative algorithm, can improve the response speed power-tracking, and is faster to achieve power balance. |
