Recursive Least Squares with Fading Regularization for Finite-Time Convergence without Persistent Excitation

Brian Lai, Dimitra Panagou, Dennis S. Bernstein

This paper extends recursive least squares (RLS) to include time-varying regularization. This extension provides flexibility for updating the least squares regularization term in r…

Adaptive Kalman Filtering Developed from Recursive Least Squares Forgetting Algorithms

Brian Lai, Dennis S. Bernstein

Recursive least squares (RLS) is derived as the recursive minimizer of the least-squares cost function. Moreover, it is well known that RLS is a special case of the Kalman filter.…

Convergence of Recursive Least Squares Based Input/Output System Identification with Model Order Mismatch

Brian Lai, Dennis S. Bernstein

Discrete-time input/output models, also called infinite impulse response (IIR) models or autoregressive moving average (ARMA) models, are useful for online identification as they c…

SIFt-RLS: Subspace of Information Forgetting Recursive Least Squares

Brian Lai, Dennis S. Bernstein

This paper presents subspace of information forgetting recursive least squares (SIFt-RLS), a directional forgetting algorithm which, at each step, forgets only in row space of the…

Efficient Batch and Recursive Least Squares for Matrix Parameter Estimation

Brian Lai, Dennis S. Bernstein

Traditionally, batch least squares (BLS) and recursive least squares (RLS) are used for identification of a vector of parameters that form a linear model. In some situations, howev…

Adaptive Real-Time Numerical Differentiation with Variable-Rate Forgetting and Exponential Resetting

Shashank Verma, Brian Lai, Dennis S. Bernstein

Digital PID control requires a differencing operation to implement the D gain. In order to suppress the effects of noisy data, the traditional approach is to filter the data, where…

Generalized Forgetting Recursive Least Squares: Stability and Robustness Guarantees

Brian Lai, Dennis S. Bernstein

This work presents generalized forgetting recursive least squares (GF-RLS), a generalization of recursive least squares (RLS) that encompasses many extensions of RLS as special cas…
