<p>A current-to-pressure converter sets line pressure to a desired pressure indicated by the current. A circuit senses the line pressure and the current, receives compensation, and outputs a compensated difference between line and desired pressures. A first driver circuit provides actuator drive based on the compensated output. The actuator controls the line pressure, but presents a temperature sensitive, reactive load to the actuator drive. A simulated load simulates a resistive part of the actuator load. A second driver provides simulated drive to the simulated load. The second driver generates the compensation which simulates actuator drive parameters, but is isolated from reactive effects and temperature sensitivity of the actuator.</p> |
