Abstract

A novel flow rate compensated model is proposed to eliminate the square-root nonlinearity of electro-hydraulic systems with time-varying parameters and uncertain nonlinearities. A simplified direct adaptive robust control method using this new model is presented and the transient performance and stability of the controller is proved. The simulation and experimental results show that simplified direct adaptive robust controller with proposed flow rate compensated model can achieve a good performance for given tracking task.
