Abstract :
The concept of control Lyapunov function has proven a useful tool for designing robust control laws for nonlinear systems. Recently, this concept has been extended to time-delay systems in the form of control Lyapunov Razumikhin functions and control Lyapunov Krasovsky functionals (CLKF). Universal formulas, such as Sontag´s formula (1989) and domination redesign formula, apply to CLKF´s and achieve robustness properties that include infinite gain margin. In this paper we illustrate the application of a CLKF based design on a model of turbocharged diesel engine with exhaust gas recirculation valve that includes intake-to-exhaust transport delay
