Abstract :

In this paper, the method of modern control approach for the design of controller and observer is used. Other functions such as neural controllers - or fuzzy sliding mode control can be found in this work and the results are compared. First, a dynamic model of the servo valve is intended for the governing equations in state-space form expression are obtained. Due to the system integrator is expressed by the non-zero, The servo system of a full-order state observer pole positioning method to measure the dominant pole, Bessel and ITAE is designed and evaluated. Response to a step input to the system is designed and the observer's response to initial conditions. The curves show the comparison between systems is designed to do.
