5.At last, the active and passive methods to prevent helicopter from vortex-ring accident are put forward, and it is pointed that the vortex-ring alarm device is the effective routine to reduce helicopter vortex-ring state flight accident and assure flight safety, and it is suggested to form the system of helicopter vortex-ring prevention.
9.Abstract: A methodology to reduce the input fuzzy sets with the hyperplane of generalized state error is discussed in this paper based on sliding mode control (SMC) theory,a method of varying nonlinear fuzzy sets range using some parameter is proposed ,and some internal properties of fuzzy controller is analyzed to show that the fuzzy controller outperform the PID controller,such as the stability and steady-state error.
