摘　　要：该文针对新一代轻量化坦克在高速行驶时的身管稳定问题,提出一种高精度控制策略。基于负载系统的动力学特性,建立含不确定性的坦克炮稳定系统受控状态空间方程;考虑射击门及稳定精度限制,构建系统状态的不等式约束,并完成受限状态转换;量化系统不确定性边界,结合约束跟随控制思想,开展系统不确定控制设计。研究表明,所提方法可综合处理坦克炮稳定系统的强非线性和复杂时变不确定性,实现系统稳定精度可控,为复杂机械系统的时变不确定性抑制和误差控制提供理论指导。This paper proposes a high-precision control strategy to solve the barrel stability problem of the new generation lightweight tank at high speed.Firstly,the controlled state space equation of tank gun stabilization systems with uncertainty is established based on the dynamics of load systems.Second,inequality constraints about the system states are constructed considering the firing gates and stabilizing accuracy constraints,and constrained state transitions are accomplished.Finally,the system uncertainty control design is conducted by quantifying the system uncertainty boundaries and combining the constraint following control idea.The results show that the proposed method can comprehensively deal with the strong nonlinearity and complex time-varying uncertainty of the tank gun stabilization system,and realize control of the system stabilization accuracy.Furthermore,it provides theoretical guidance for time-varying uncertainty suppression control and error control of complex mechanical systems.
