摘要
针对具有复杂不确定性的双电机驱动舰载火炮随动系统,提出一种能实时评估系统复杂不确定性综合影响参数,实现火炮随动系统双向稳定控制的自适应鲁棒控制策略。介绍了舰载火炮随动系统结构组成,构建机电一体化非线性耦合动力学模型;定义跟踪误差,分析系统不确定性,构建状态空间方程;设计不确定表征参数α,基于α设计自适应律和自适应鲁棒控制器,并通过实用稳定性理论证明受控系统的稳定性。仿真实验表明,在海浪冲击、传动误差等不确定性干扰下,该控制器可使随动系统快速跟踪目标信号并保持稳定状态。
For the dual-motor-driven shipborne gun servo system with complex uncertainties,an adaptive robust control strategy is proposed.This control strategy can achieve bidirectional stable control of the gun servo system and simultaneously evaluate the comprehensive impact parameters of the system’s complex uncertainties in real time.The structural composition of the shipborne gun servo system is introduced and a mechatronic integrated nonlinear coupled dynamic model is established.The tracking errors are defined,the system uncertainty is analyzed,and the state-space equations are built.The uncertainty characterization parameterdαis designed,the adaptive laws and an adaptive robust controller are designed based on the parameterdα,and the stability of the controlled system is proved by practical stability theory.The joint simulation experiment shows that,under the interference of such uncertainties as wave impacts and transmission errors,this controller enables the tracking system to quickly follow the target signal and maintain a stable state.
