      Robust adaptive control for a class of MIMO nonlinear systems with guaranteed error bounds 

      Xu, H.; Ioannou, Petros A. (2003)
      The design of stabilizing controllers for multiple-input-multiple-output (MIMO) nonlinear plants with unknown nonlinearities is a challenging problem. The high dimensionality coupled with the inability to identify the ...

      Robust Autocorrelation Estimation 

      Chang, Christopher C.; Politis, Dimitris Nicolas (2016)
      In this article, we introduce a new class of robust autocorrelation estimators based on interpreting the sample autocorrelation function as a linear regression. We investigate the efficiency and robustness properties of ...
