摘　　要：针对实际中含有较多的状态变量,通过目标全息反馈法将实际中比较关系放至同一个状态方程中,根据新的状态方程,逐步设计对应的李雅普诺夫函数,根据函数的正定性和导数的负定性来保证系统的稳定性。由于控制函数的表达式中含有较多的系统参数,设计了二阶的扩张状态跟踪器来跟踪和补偿这些扰动,保证系统的鲁棒性。Considering the actual state variables, the objective holographic feedback method is adopted to incorporate the relevant variables into the same state equation, whereby the corresponding Lyapunov function is gradually formula- ted. The system stability is ensured based on the function positive definiteness and the derivative negative definite- ness. Since the control function of the expression comprises more system parameters, the second-order extended state tracker is designed to track and compensate these disturbances, with a view to ensuring the system robustness.
