| Summary |
"The problem is to develop a phase-lead compensation network for a servomechanism which will not reduce the low-frequency gain and thus decrease the velocity-lag error. The principal part of this thesis deals with the design of such an active phase-lead network. The active network does not have d-c coupling; this eliminates drift problems. To illustrate an active phase-lead network a simple second order servomechanism is used as a basis for comparing three methods of compensation. The first method is compensation with a conventional phase-lead network with a gain decrease. The second method is compensation with a conventional phase-lead network with a gain increase. The third method is compensation with an active phase-lead network with no gain change. The three compensated systems were selected to have about the same peak overshoot but not necessarily the same rise time. The basic servomechanism was simulated on the MSM Analog Computer and used to design the active phase-lead network. Photographic recordings were made to illustrate the effectiveness of the design"--Introduction, leaf 1. |
