Design on the digital electro-hydraulic Servo System of the Hydroturbine Governor
In this paper, a digital electro-hydraulic servo system is built base on actual requirement of some medium and large hydropower stations. Then the structure and working principle of digital servo system on a new digital hydroturbine governor were introduced. And the structural parameters of this digital servo system were scientifically analyzed and theoretically calculated. In the end, we get a digital servo system whose structure was rational and function was satisfactory.
In this paper,a control model of stepper motor after studying on its three phases hybrid drive was set up, and the potential relation between the motor speed curve and its motion performance in a real drive system was found out.Then the optimization control of precise and fast orientation of the stepper motor was given with MATLAB simulink.
