Many control systems are currently being controlled by digital computers. However, utilization of hydraulic servomechanisms for the mechanical power output stages of these control systems, which employ the step input command as the control signal, requires soft characteristics, since these servomechanisms must not incur excessive overshoot and/or high acceleration, especially in the mass loaded condition. The subject of this paper is the position control system, composed of a servo valve and an actuator(cylinder), into a soft response characteristics type servomechanism, which moves a relatively longer distance with high speed and high accuracy. This is an unexploited field for hydraulic servomechanisms. In this paper, the velocity feedback signal is used as a damping augmentator to obtain soft response characteristics. In the first step, a mathematical model of a hydraulic servomechanism is established in non-dimensional form under a mass loaded condition. Then, three parameters, determining the characteristics of the hydraulic system, are defind: These are, (1)the servo valve time constant, (2)inertia load, and (3)ratio of position to velocity feedback gain. Finally, simulation studies and discussions of the calculation results are conducted regarding the influence of these three parameters, especially on shock acceleration and overshoot for step input signal. |
