CONTROL OF FOURTH ORDER SYSTEMS FOR EXPONENTIAL SETTLING AND QUASI- OPTIMUM TIME RESPONSE

Abstract

Linear state signal feedback is used to obtain exponential response from fourth order systems. Characteristic equation roots are selected to provide the desired exponential response with constraint on initial conditions and system acceleration. A digital computer root locus program is developed to determine feedback coefficients in a manner which minimizes the possibility of oscillatory response in the presence of state sensor errors. The effect of noise on the state signal is investigated and a sample data filtering technique developed. A quasi-optimum time technique utilizing second order switching logic for initial control effort and linear feedback for terminal control is developed.
