The dynamical behavior of a cantilever beam subject to parametric excitation is investigated. The method of multiple scale perturbation technique is applied to obtain the solution up to the second order approximation. At first we studied the system behavior without control and the effect of parameters at this case. The active control of negative feedback with linear and cubic velocity is used to vibration control. It can be seen that the linear control is more effective than the cubic control.fatcat:uifoj2avdnapxhrtswrsdhm67u
