%X To design an accurate tracking control for the electro-hydraulic servo position system with uncertain coefficient in control input, an improved adaptive Backstepping controller design method is presented. By using the equivalent model transformation and selecting a proper Lyapunov function, the nesting problem caused by the mutual inclusion of parameter adaptive law and control input is effectively solved. This method is also applied to design a hydraulic drive servo system for a continuous cast mold and validate the stability. Simulation results show that the designed controller works with high robustness and desirable tracking performance.
