CONTROL DEVICE FOR LINEAR SOLENOID Russian patent published in 2020 - IPC F02D41/14 G05B13/04 

FIELD: machine building.

SUBSTANCE: invention relates to automotive engine control systems, in particular to adaptation of control system parameters with feedback for control of linear solenoid for automatic transmission. Disclosed is control equipment for control of linear solenoid by control of control current supplied to linear solenoid through control with feedback. Control with feedback is performed by means of control system with feedback, having parameters, which are determined in compliance with inverse linear quadratic projection (ILQ-design) method. In the frequency characteristic of the amplification of the transfer function, which is the ratio of the output to the disturbances in the feedback control system, the gain is lower than 0 [dB] over all frequency bands.

EFFECT: technical result is provision of control for linear solenoid, which allows reduction of adaptation stages for parameters adaptation.
