This article investigates the bumpless transfer (BT) control problem of switched systems with unmeasured states. Note that the control input signal of the switched system jumps when switching occurs, which may adversely affect the performance of switched systems. By introducing a modified state observer and an auxiliary continuous control signal, a novel description of the BT performance for the system is presented. Moreover, a compensation-based dynamic BT controller and a bump-dependent switching law are designed to solve the BT control problem. As a result, the developed control method ensures the stability of the closed-loop system while maintaining BT performance. The validation of the results can be provided by applying the proposed BT control method to an example of an aero-engine control system.

通过动态反馈和凸块相关开关定律对开关系统进行无扰动传输控制


本文研究了具有未测量状态的切换系统的无扰动传递 (BT) 控制问题。请注意，切换发生时切换系统的控制输入信号会发生跳变，这可能会对切换系统的性能产生不利影响。通过引入修正状态观测器和辅助连续控制信号，提出了系统 BT 性能的新颖描述。此外，还设计了基于补偿的动态BT控制器和凸块相关切换律来解决BT控制问题。因此，所开发的控制方法在保持BT性能的同时确保了闭环系统的稳定性。通过将所提出的 BT 控制方法应用于航空发动机控制系统的示例，可以验证结果。
