Feasibility Study and Experimental Model of an Optimal Control Servomechanism
Abstract
Research is concerned with the construction of a feasibility model demonstrating the principles of optimal discontinuous control for servo motors. The servomechanism to be constructed will be optimally designed with respect to inputs of the type, step plus ramp disturbance, and will be self adaptive to torque variations in the load. There appear to be 2 design approaches to the synthesis of the optimal switching function. One would be to construct an analog of the switching function using conventional analog computer techniques, such as logarithmic amplifiers, multipliers, dividers and other nonlinear element to produce, in real time, subject to the state variations of the error and error rate in the phase-plane, an optimal discontinuous forcing function. A second technique is to construct the switching function faster than real time through the use of passive analog elements. This technique would run the linear plant to the origin, in the phase plane, many times faster than real time. Noting the error and switching the forcing function will match that predicted condition. This second technique was adopted.
