      Roadway traffic controller design for automated highway systems 

      Chien, C. C.; Zhang, Y.; Stotsky, A.; Ioannou, Petros A. (IEEE, 1994)
      For manual driving, the traffic flow is often irregular, unstable leading to congestion and to low traffic flow rate during minor incidents. These irregularities are due to variation of vehicle speeds and headways that are ...

      Robust adaptive control for a class of mimo nonlinear systems 

      Xu, H.; Ioannou, Petros A. (2002)
      The design of stabilizing controllers for nonlinear plants with unknown nonlinearities is a challenging problem. The inability to identify the nonlinearities on-line or off-line accurately motivates the design of stabilizing ...

      Robust adaptive control-a modified scheme 

      Tao, G.; Ioannou, Petros A. (1991)
      A normalizing signal that does not require the knowledge of the stability margin of the unmodelled dynamics is used in robust model reference adaptive control (MRAC) for plants with an enlarged class of unmodelled dynamics. ...
