A control system for controlling a variable of a device by an end element is disclosed. The control system has as its input a magnetostrictive position sensing probe for measuring the value of the variable of the device at time intervals and a digital controller reading the value from the magnetostrictive position sensing probe and having an output and means for calculating control output from the updated value of the variable during the time interval. The digital controller is close coupled to the magnetostrictive position sensing probe to permit time intervals that are very short, such as 500 microseconds to 1 millisecond.
