Abstract

This paper addresses the analysis, design, and application of observer-based nonlinear controls by combining feedback linearization (FBL) and backstepping (BS) techniques with Luenberger observers. Complete development of observer-based controls is presented for a bioprocess. Controllers using input-output feedback linearization and backstepping techniques are designed first, assuming that all states are available for feedback. Next, the construction of observer in the transformed domain is presented based on input-output feedback linearization. This approach is then extended to observer design based on backstepping approach using the error equation resulted from the backstepping design procedure. Simulation results demonstrating the effectiveness of the techniques developed are presented and compared.
利用反馈线性化、反演和Luenberger观测器的生物过程非线性控制
本文通过将反馈线性化(FBL)和退步(BS)技术与Luenberger观测器相结合,讨论了基于观测器的非线性控制的分析、设计和应用。完整的发展基于观察者的控制提出了一个生物过程。首先设计了使用输入输出反馈线性化和反演技术的控制器,假设所有状态都可用于反馈。其次,提出了基于输入-输出反馈线性化的变换域观测器构造方法。然后利用反演设计过程得到的误差方程,将该方法扩展到基于反演方法的观测器设计中。仿真结果验证了所开发技术的有效性并进行了比较。
