A Vibroacoustic Application of Identification and Control for Linear Time-Varying Systems
نویسندگان
چکیده
Abstract: This paper presents an application of H2 and H∞ gain-scheduled and robust state feedback control for a time-varying vibroacoustic setup whose dynamics is highly sensitive to variation in the ambient temperature. An LPV model is derived for this system using the State-space Model Interpolation of Local Estimates (SMILE) technique. This approach interpolates linear time-invariant models estimated at distinct operating conditions of the system (in this case, different temperatures). The obtained LPV model is used in recently developed gain-scheduled and robust H2 and H∞ synthesis procedures that can consider a priori known bounds on the rate of parameter variation.

Potentials of Evolving Linear Models in Tracking Control Design for Nonlinear Variable Structure Systems
Evolving models have found applications in many real world systems. In this paper, potentials of the Evolving Linear Models (ELMs) in tracking control design for nonlinear variable structure systems are introduced. At first, an ELM is introduced as a dynamic single input, single output (SISO) linear model whose parameters as well as dynamic orders of input and output signals can change through ...
متن کاملAdaptive fuzzy pole placement for stabilization of non-linear systems
A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...

This article presents a fuzzy robust Mixed - Sensitivity Gain - Scheduled H controller based on the Loop -Shaping methodology for a class of MIMO uncertain nonlinear Time - Varying systems. In order to design this controller, the nonlinear parameter - dependent plant is first modeled as a set of linear subsystems by Takagi and Sugeno’s (T - S) fuzzy approach. Both Loop - Shaping methodology and...
متن کاملApplication to Adaptive Control to Synchronous Machine Excitation
Self-tuning adaptive control technique has the advantage of being able to track the system operating conditions so that satisfactory control action can always be produced. Self-tuning algorithms can be implemented easily. Because the power systems are usually time varying non-linear systems and their parameters vary, adaptive controllers are very suitable for power systems. Characteristics of a...
