摘要
研究了如何利用Washout滤波器的混沌控制技术来控制Colpitts振荡器中的混沌.首先得到振荡电路的归一化状态方程及基于Washout滤波器技术的控制方程,然后通过调整滤波器的控制参数,将混沌状态的Colpitts振荡器控制到稳定平衡点或周期振荡状态,最后分析了控制结果,进行了数值仿真,验证了该控制方法的有效性.
Control of chaos in Colpitts oscillator by using Washout filter is studied.Firstly,normalization of the circuit and controlling equations are derived based on Washout filter technique.Then by adjusting the control parameters,chaos in Colpitts oscillator is controlled to stable equilibrium point or periodic state.Finally,the controlling result is analyzed simulation is done and the effectiveness of this control method is verified.
