| description | A method is described for controlling a solenoid-operated fluid valve having an output hydraulic pressure that varies in accordance with an input solenoid control current delivered from a drive circuit. A model is provided characterizing the plant dynamics of the solenoid-operated fluid valve and the drive circuit where the model is dependent on at least one operating parameter. The method, during operation, involves measuring the value of the operating parameter and adjusting based on the measured operating parameter value one or more gain constants to be used in a selected control strategy. The model is used in adjusting the gains. Finally, the method involves determining a required solenoid control current according to the control strategy with the now dynamically-adjusted gain constants. The control strategy may be a PI control strategy. The model-based system allows easy migration of the general control strategy to different hardware configurations by developing target system specific data for the model. |
