Nonlinear H-infinity control for switched reluctance machines

H-Infinity Controller Design for the Switched Reluctance Machine

Abstract—The switched reluctance machine (SRM) has undeniable qualities in terms of low cost and mechanical robustness. However, its highly nonlinear character and its uncertain parameters justify the development of complicated controls. In this paper, authors present the design of a robust H-infinity current controller for an 8/6 SRM with taking into account the nonlinearity of the SRM and wit...

Voltage control of switched reluctance machines for Hybrid Electric Vehicles

The rugged low-cost construction and constant power profile of a switched reluctance motor (SRM) make it suitable for hybrid electric vehicles (HEVs). This paper describes the development of a voltage-based control strategy for a SRM. The controller design is influenced by project constraints and goals as well as the use of a new power topology. A prototype SRM and controller were built and ful...

Hierarchical Distributed Motion Control for Multiple Linear Switched Reluctance Machines

This paper investigates a distributed, coordinated motion control network based on multiple direct-drive, linear switched reluctance machines (LSRMs). A hierarchical, two-level synchronization control strategy is proposed for the four LSRMs based motion control network. The high-level, reference signals agreement algorithm is first employed to correct the asynchronous behaviors of the position ...

Nonlinear H-infinity Control: an Lmi Approach

In this paper, we consider the problem of robust H-infinity Control for a class of uncertain nonlinear systems. We derive LMI conditions for analyzing regional robust stability and performance based on Lyapunov functions which are polynomial functions of the state and uncertain parameters. More specifically, we provide an energy bound on the input disturbance which guarantees that the state of ...
