Title: Speed control method of cylinder in hydraulic system
Inventor: TANIDO KOUJI
IPC: B29C45/82
Filed: 1982-08-26
Abstract: PURPOSE:To ensure quick response, stable and accurate control by means of a simple control system where the speed of a hydraulic cylinder is controlled to be varied suddenly to a large extent by performing open loop control in the transient condition immediately after a set value is modified and then shifting the control to feedback control when a controlled object comes into an approximately normal condition. CONSTITUTION:Based on a speed setting signal from a program setter 13 which sequentially switches and generates a speed setting value preset in accordance with variation of a cylinder stroke signal from a position detector 12, open loop control and feedback control are switched and a speed-pulse number conversion circuit 21 calcurates a pulse number which corresponds to the preset value. The number is then converted into a pulse signal in a pulse generating circuit 22 and fed via a driving device 15 and a pulse motor 10 to control an opening of a flow rate regulting valve 11. Said pulse signals are generated at the maximum rate which a cylinder speed can follow and at a rate which causes no overshoot. When the speed of the hydraulic cylinder 1 comes almost into the normal condition, the open loop control is switched to the feedback control loop.
