Improved Transient Response in Adaptive Control Using Projection Algorithms and Closed Loop Reference Models

چکیده
This paper explores the properties of adaptive systems with closed–loop reference models. Historically, reference models in adaptive systems run open–loop in parallel with the plant and controller, using no information from the plant or controller to alter the trajectory of the reference system. Closed–loop reference models on the other hand use information from the plant to alter the reference trajectory. Using the extra design freedom available in closed–loop reference models, we design adaptive controllers that are (a) stable, and (b) have improved transient properties. Numerical studies that complement theoretical derivations are also reported.

متن کاملPosition Control Improvement of Permanent Magnet Motor Using Model Predictive Control
Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...

متن کاملDesign and Analysis of a Novel L1 Adaptive Control Architecture With Guaranteed Transient Performance
Conventional Model Reference Adaptive Controller (MRAC), while providing an architecture for control of systems in the presence of parametric uncertainties, offers no means for characterizing the system’s input/output performance during the transient phase. Application of adaptive controllers was therefore largely restricted due to the fact that the system uncertainties during the transient hav...
متن کاملA Family of Selective Partial Update Affine Projection Adaptive Filtering Algorithms
In this paper we present a general formalism for the establishment of the family of selective partial update affine projection algorithms (SPU-APA). The SPU-APA, the SPU regularized APA (SPU-R-APA), the SPU partial rank algorithm (SPU-PRA), the SPU binormalized data reusing least mean squares (SPU-BNDR-LMS), and the SPU normalized LMS with orthogonal correction factors (SPU-NLMS-OCF) algorithms...
