Adaptive robust control and oscillation estimation for offshore mechanical systems

Project Period (FY)： 2016/04 - 2019/03 Investigator(s): Masayoshi Toda

Grant-in-Aid for Scientific Research(C) Principal Investigator 16K06902

In this study, we consider motion control systems for ocean mechanical systems subject to wave-induced base oscillation such as offshore/onboard cranes, radar attitude control systems, and so on. In this research term, we have developed an adaptive robust control method and an adaptive robust oscillation estimation one to cope with frequency variation due to ship motion . The control method is based on switching multiple H∞ controllers for respective frequencies. The estimation method is based on selectively combining a Kalaman filter with adaptive gain and the conventional H∞ filter. Evaluations were conducted for the control method by simulations and for the estimation method by not only simulations but also model experiments using a gyro sensor respectively, and consequently those results have shown their effectiveness.
