The algorithm for optimizing the parameters of the measuring system were proposed; The distribution and propagation patterns of the measured errors for all the harmonics of roundness were studied in detail; A software for correcting the errors caused by the measurement error of the angle positions of the probes and the sensitivity difference between three probes was presented.

While trying to get a grasp of the septile aspect, I went back to John Addey (1920 1982), a key voice in bringing Pythagorean understanding of numbers into modern astrology. He wrote Harmonics in Astrology in 1976; it is now back in print after many years. He writes that the number seven (and the 7th harmonic)"is a difficult number to pin down" and "somewhat elusive to interpret."

为了试图给7分相位一个浅显的解释，我找到了历史上的一位占星家，名叫 John Addey ，将毕达哥拉斯对数字的理解带进了现代占星学，他1976年出版了一本《占星中的数字和谐》，书中有关数字7和7分相位，他写道"它是一个很难确定，很难下结论的数字"并且"不太容易解释和捉摸"。

ABSTRACT The purpose of this dissertation is to study the problem of modeling of non—minimum phase random signals, and the retrieval of harmonics in noise by using higher—order statistics as a signal processing tool.

In order to overcome the shortcoming of PI controller in harmonics control, the repetitive control and PI control are combined and used in the closed-loop control of TSMC; The problem of conventional repetitive controller is pointed out and a modified repetitive control method is proposed: To avoid the influence of no-periodical disturbance on the control action of repetitive controller, the error caused by no-periodical disturbance is identified and discarded.

针对PI控制器对谐波控制的不足，将重复控制技术与PI控制相结合，应用于TSMC逆变级的闭环控制中；在此基础上提出了重复控制器的改进方案：对由非周期性扰动引起的误差不进行记忆，以避免其对重复控制器的控制动作产生干扰。
