摘　　要：在快速变化的干扰环境下,无线通信系统传输可靠性会受到很大影响。为提升快速时变干扰环境下无线通信系统传输的可靠性,该文提出一种基于干扰观测的无线通信系统抗干扰功率控制算法。该算法首先将受到干扰影响的无线通信系统建模为广义稳定性控制系统,并采用干扰观测器生成系统状态受干扰影响的估计值。然后通过利用估计值来预测未来的跟踪误差和稳态的控制输入,优化系统的控制策略以实现对干扰环境的自适应调整。最后仿真结果表明,与传统方法相比,所提算法能够快速响应干扰变化,显著提高系统在快速时变恶意干扰下传输的可靠性,提高了系统对干扰环境的适应能力。In the rapidly changing jamming environment,the transmission reliability of wireless communication systems can be significantly impacted.To enhance the transmission reliability of wireless communication systems under such fast-changing jamming conditions,a disturbance observer-based anti-jamming power control algorithm is proposed.The proposed algorithm first models the wireless communication system affected by jamming as a generalized stability control system and utilizes a disturbance observer to generate estimated values of the system state impacted by jamming.Subsequently,by using these estimated values to predict future tracking errors and steady-state control inputs,the algorithm optimizes the system's control strategy to achieve adaptive adjustments in response to the jamming environment.The simulation results demonstrate that,compared to conventional methods,the proposed algorithm can rapidly respond to changes in jamming,significantly improving the system’s transmission reliability under rapidly changing malicious jamming,and enhancing the system’s adaptability to jamming environments.
