         Abstract--Lyapunov functions are an important tool in         
         nonlinear control systems theory. This talk presents new      
         Lyapunov-based adaptive tracking control results for nonlinear
         systems in feedback form with multiple inputs and unknown     
         high-frequency control gains. Our adaptive controllers yield  
         uniform global asymptotic stability for the error dynamics,   
         which implies parameter estimation and tracking for the       
         original systems. We demonstrate our work using a tracking    
         problem for a brushless DC motor turning a mechanical load.   
         Then we present a new class of dilution rate feedback         
         controllers for two-species chemostat models with Haldane     
         uptake functions where the species concentrations are measured
         with an unknown time delay.
