This paper deals with the robust boundary stabilization problem of hyperbolic partial differential equations (PDEs) subject to boundary uncertainties. These systems include a second-order undamped wave equation and a first-order delay system. By taking the integral transformation, we obtain a nominal PDE with asymptotic stability in the new coordinates when an appropriate boundary control input is...
A new model reference direct adaptive sliding mode control (MRDASMC) approach for electromechanical actuator (EMA) is presented. Uncertainties with parameter variation, external load disturbance, nonlinear structure and unmodelled dynamics in the system are treated as a lumped uncertainty. The lumped uncertainty is estimated without the bounds known in advance. A switching function is employed to...
