Approximate Analysis of Stochastic Relay Control Systems. II

摘要

An investigation was conducted into the technique of replacing a relay by a correlation transforming device in the analysis of stochastic relay control systems. The aim was to obtain more reliable accuracy estimates than with the use of analogue simulations. Differential equations obtained for system autocorrelation functions were solved analytically and by computation. The approach yielded less accurate results than Booton's statistical linearization precedure. The treatment applied in Part I to a first order relay control system with a white noise disturbance was applied here to a second order system. Earlier results concerning the ned to assume a Gaussian input were confirmed.
