Approved for public release; distribution is unlimited / A group of lesser used analog control system design techniques, generally termed parameter plane methods, is examined through the use of an IBM compatible microcomputer program developed as part of this thesis. The coefficients of a system's characteristic polynomial are determined by the plant and any added compensators. As these coefficients are varied , so too are the roots of the characteristic equation and therefore the system response in terms of bandwidth, settling time, etc. In the parameter plane method, a designer selects two parameters of a system's compensator(s) . The parameters commonly represent such attributes as a compensator gain, pole, or zero but can be any linear system function. One or more system characteristics dictating desired system performance, such as relative damping or undamped natural frequency, are computer model inputs. The associated parameter values to achieve the input characteristics are output in graphical and/or tabular form. / http://archive.org/details/parameterplanean00kran / Lieutenant Commander, United States Navy

The aim of this diploma thesis is reconstruction of gearbox testing rig. Modernization will allow fully automatic long-term gearbox tests according to pre-defined test parameters. The first part of thesis describes commercial and scientific solutions of used testing rigs. Individual solutions are inspected and evaluated for applicability to upgrade the testing rig. The second part of diploma thesis deals with selection of purchased components for allowing automatic drive, design concepts, selection of appropriate design, assembly and installation of control board and calibration of used components. This part of diploma thesis deals with analysing of software solution made for automatic drive too. The output of this work is a functional sample of control hardware and software for automatic and manual control which contains recording of measured data.
