Abstract
The controller is a logical network which, when interfaced with a mechanical system or an electromechanical system, will cause the output variable of the system to closely follow any command signal received. It comprises shift registers, memory banks, accumulators, arithmetic units and preferably no software. Universal Controller keeps the error between the output of the model and the output of the control system small, regardless of the transfer function of the controlled system by adjusting a number of gains in its internal feedback loop in accordance with that error. It therefore can be applied to an arbitrary electromechanical system without prior knowledge of its transfer function.
