【Abstract】 The optimal feedback gain and maximum decay rate of a single link flexible Euler-Bernoulli beam under shear force feedback control has been obtained by using the Legendre spectral method. The numerical results show that the noncollocated control can improve the decay rate of the beam. Moreover, the open loop noncollocated control system is a minimum phase system.更多还原
