ABSTRACT:
A speed control system is disclosed for driving a motor at .omega. radians per second for the purpose of rolling material in a hollow cylindrical form with preselected outside and inside diameter OD and ID respectively. The material to be rolled is fed to the coiler at a linear speed s. An integrator having dual polarity inputs delivers an output .omega./s. A detector has inputs connected to receive a signal which is a function of the preselected diameters OD and ID respectively and the integrated output .omega./s, and an output connected to the dual polarity integrator inputs for selectively and successively activating one of the dual inputs for determining the direction of integration. A multiplier receives the integrated output and delivers multiplied products .omega..sup.2 /s .sup.2 .omega..sup.3 /s.sup.2, .omega..sup.4 /s.sup.2. A signal shaper receives these multiplied products and delivers new products a.omega..sup.2 /s.sup.2, b.omega..sup.3 /s.sup.2, and c.omega..sup.4 /s.sup.2 where a,b,care preselected constants. A summer sums the products a.omega..sup.2 /s.sup.2, b.omega..sup.3 /s.sup.2 and c.omega..sup.4 /s.sup.2 and delivers the summed signal: ##EQU1## TO THE DUAL INPUTS OF THE INTEGRATOR. An additional multiplier receives the integration signal .omega./s, multiplies it by s, and delivers the signal .omega. which is the speed reference signal for the motor.
