英文摘要

      A parameter adaptive sliding mode control method and the parameter adaptive law are given aiming at the gyroscopic chaos synchronization. The parameter adaptive sliding mode control has completely avoided the high frequency switching caused by the symbolic function of the sliding mode surface and effectively eliminated the high frequency chattering in the existing sliding mode control. This method features a small calculation amount and can track the main chaotic system quickly without depending on the mathematical model of the controlled chaotic system. The analysis and simulation experiments based on the time and complex frequency domains both show that the parameter adaptive sliding mode control method is characterized by global asymptotic stability. The research results indicate that the control method proposed in this paper not only features fast response speed, high control accuracy and good anti-disturbance robustness, Therefore, it has important theoretical significance and application value in the field of control engineering.
