| Summary: | Many methods have been proposed and tested In the
past to obtain an optimal response for step Inputs to
automatic feedback control systems. Most of these
methods have led to the use of sophisticated control
devices ranging from small analog to large digital
computers. Here the possibility of a simplified
switching logic combined with an open-closed loop
servome onanism is investigated. Deadbeat response to
step inputs was the object of this study rather than
a time optimal response. Two types of logic were
investigated. A time invariant controller was analyzed,
built and tested. The system works on the principle
of constant switching times with the output being
controlled by an open loop driving voltage which is
proportional to the input step size. At the completion
of the open loop mode of operations, the system is
returned to the normal closed loop mode. |
