Bumpless Transfer Control for Switched Systems via a Dynamic Feedback and a Bump-Dependent Switching Law
研究切换系统中控制信号切换时产生跳跃的问题,通过改进状态观测器和辅助连续信号,设计动态控制器和依赖凸点的切换律,保证系统稳定和无扰切换性能,并用于航空发动机控制。
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.
