Without introducing a discrete model,unstable continuous flows in a neighbourbood of an unstable stationary point can be stabillized.The linear part of the vector field of distrubing the flow can be managed to become the state vairable multiplied by a negative constant.The nonlinear part of the vector field keeps to be unchanged,therefore flows far away from the stationary point are almost unaffected by the disturbance.The control method is easy to be used.even for practical problems for which a priori analytical knowledge of system dynamics is unavailable. 相似文献
