Abstract

The purpose of the article - to develop a mathematical model and block diagram of nonlinear control systems, which are algorithms of dynamic characteristics and basis of calculation and to analyze the new hydraulic system Design/methodology/approach :The new design of hydraulic system two-stage hydraulic torque by changing the structural elements and connections to ensure the improvement of its dynamic characteristics and indicators of process control [4]. Developed hydraulic torque amplifier ensures drive object as in tracking mode and fast moving (fast carts, disqualification, etc.). Object no tracking mode without entering into hydraulic system additional hydraulic. Conclusion: The hydraulic torque amplifier allows to improve the hydraulic characteristics, namely to reduce area and increase the rigidity nechuttyevosti drive in the zone of relatively low pressures, increase allowable speed and velocity tracking movements in neslidkuyuchomu mode. Mathematical model and block diagram allows, using the methods of the theory of automatic control, the quality of hydraulic transition or frequency characteristics relative to managing or perturbation signals, and create the possibility of developing automated systems with predetermined quality indices .
