Regulator Characteristics: A Conparision of Two Speed Regulations

The importance of the transient characteristics of analog regulators used on paper machine drives is shown. The speed regulator was chosen as a model since it is the regulator that is most often used. Two different forms of speed regulators were used to demonstrate the differences between different forms of regulators with comments on these differences. A program from the General Electric time-sharing system was used to simulate the two speed regulators, subjecting the regulators to changes in reference and load to determine their transient performance characteristics. The traces of the regulated values are discussed as to their behavior and possible effects when used as a regulator on a paper machine drive.
