The electronic servomechanism simulator

A LARGE-SCALE analogue computer, capable of solving the general equations of motion of an aircraft, to be used primarily in the development of aircraft control systems is being developed at the Massachusetts Institute of Technology. The electronic servomechanism simulator is included as a portion of the computer to represent electrically the dynamic behavior of the servomechanisms which position the aircraft control surfaces. These servomechanisms usually are designed to operate linearly. However, a servomechanism which is small enough to be practical occasionally will be required to operate at the extreme limits of its physical capacity — beyond its linear range.
