Singularity-free multivariable model reference adaptive control
IEEE Transactions on Automatic Control, 1993 Summary: We propose a way to solve the problem of singularities in model reference adaptive control of linear multi-input multi-output systems using a parameter modification procedure based on the least squares covariance matrix inverse. The scheme does not require any explicit prior knowledge about the leading coefficient matrix associated with the ...

Model‐Free Adaptive Control Algorithm with Data Dropout Compensation [PDF]
Mathematical Problems in Engineering, 2012 The convergence of model‐free adaptive control (MFAC) algorithm can be guaranteed when the system is subject to measurement data dropout. The system output convergent speed gets slower as dropout rate increases. This paper proposes a MFAC algorithm with data compensation. The missing data is first estimated using the dynamical linearization method, and
