Abstract New technological advances are changing the way robotics designed for safe and dependable physical human–robot interaction human-like prosthesis. Outstanding examples adoption of soft covers, compliant transmission elements, motion control laws that allow behavior in event collisions while preserving accuracy performance during free space. In this scenario, there is growing interest va...

Because of the randomness wind speed and nonlinearity dynamic equation variable pitch control, it is difficult to establish an accurate floating fan. In view this situation, paper takes 5 MW turbine NREL (National Renewable Energy Laboratory) as research object, establishes under basic control FAST, uses L-M (nonlinear least square method) identify parameters system obtains model fan stability ...
