Practical Solutions To The Non-Minimum Phase And Vibration Problems Under The Disturbance Rejection Paradigm, Shen Zhao Jan 2012

Practical Solutions To The Non-Minimum Phase And Vibration Problems Under The Disturbance Rejection Paradigm, Shen Zhao

ETD Archive

This dissertation tackles two kinds of control problems under the disturbance rejection paradigm (DRP): 1) the general problem of non-minimum phase (NMP) systems, such as systems with right half plane (RHP) zeros and those with time delay 2) the specific problem of vibration, a prevailing problem facing practicing engineers in the real world of industrial control. It is shown that the DRP brings to the table a refreshingly novel way of thinking in tackling the persistently challenging problems in control. In particular, the problem of NMP has confounded researchers for decades in trying to find a satisfactory solution that is …
