模糊滑模变结构控制技术的应用研究

针对包含非线性和不确定性的坦克炮控系统，提出了一种基于模糊控制的滑模变结构控制器的设计方法。首先采用极点配置的方法确定了等效控制，再通过应用带有切换增益的鲁棒反馈控制来保证滑模到达条件，然后，利用模糊调节策略来加速到达滑动模态区并削弱抖振。本文所提出的模糊逻辑的应用是一种可计算的智能方法，针对工程问题，具有精确表达式的调整过程，使得控制策略的调整变得更加容易实现。通过仿真结果可以看出，系统得到了更好的性能指标，并且削弱了抖振。系统响应的快速性和鲁棒性都得到了提高。

Fuzzy sliding-mode variable structure control of gun control system for tanks

The authers mainly present a design method of the sliding mode variable structure controller based on the theory of fuzzy control for the gun control system of tanks, which contains nonlinearity and uncertainty. The equivalent control is first determined using pole placement. Then, the reaching condition of slide mode is guaranteed by the use of the robust feedback control with switching gains. Finally, fuzzy tuning schemes are employed to accelerate the reaching phase and reduce chattering. The practical application of fuzzy logic proposed here is a computational intelligence approach. For the engineering problems, it is easy to realize the adjustment of the control strategies with explicit expressions for tuning. The simulation results show that that high performance and attenuated chatter are achieved. The respond speed and robustness of the system are improved.
