A modified Posicast method of control with applications to higher order systems.
modifiedposicast00sohy.pdf (6.748Mb)Abstract
The control mechanism of the posicast control is completely linear. A step command is divided into two parts. In general, the second part must follow the first part by nearly one-half cycle of the transient. The total transient time is limited to about one-half cycle. There is no transient overshoot and the oscillation. The first command must deliver exactly the amount of energy needed to reach the desired output displacement. The second step and additional compensation circuit and switching or signal removes all the stored energy and locks the system. The writer wishes to express his appreciation for the assistance and encouragement given him by Professor George J. Thaler in this project
