摘　　要：针对带有内部不确定性及外部扰动的陀螺仪混沌系统的同步问题,提出了一种参数自适应滑模控制方法,并给出参数自适应律.该方法不依赖被控混沌系统的数学模型,可以快速跟踪主混沌系统.时域及复频域理论分析表明,由参数自适应滑模控制器组成的闭环控制系统是全局渐近稳定的,而且参数自适应滑模控制器具有良好的抗扰动鲁棒性.仿真结果表明该控制方法计算量小、响应速度快、控制精度高、抗扰动鲁棒性强,在非线性不确定系统控制领域具有广泛的应用价值.A parameter adaptive sliding mode control method was proposed for synchronization with internal parameter and external disturbances of the gyroscopic chaotic system,and parameter adaptive law was provided.The proposed method is not dependent on the mathematical model of the controlled plants,and can fast track the master chaotic system.The theoretical analysis of time domain and the complex frequency domain showed that the closed-loop control system composed of the parameter adaptive sliding mode controller is globally asymptotically stable and the parameter adaptive sliding mode controller has good anti-disturbance robustness.The simulation results show that the proposed method has small amount of calculation,fast response,high control precision,good anti-disturbance robustness,which has wide application value in the field of nonlinear uncertain system control.
