ANALYSIS OF OPTIMALIZING CONTROL SYSTEMS UNDER RANDOM INTERFERENCE

摘要

Two types of optimal zing control systems are analyzed and com-pared under conditions of random interference. By an approximate method, the expected hunting-loss values are calculated. The advantages and disadvantages of these control-system types can be compared under actual circumstances. In the case of Gaussian steady-state random interference, the correlation-type system has a smaller hunting loss when the interference at the input terminal is stronger than that at the output terminal, but when the situation is reversed, the gradient-type optimaxiz-ing system has smaller hunting losses.nThe calculation results give us the best step length for the gradient-type optimal zing system and the best hunting amplitude for the correlation-type optimal zing system for various noise levels. These results are important parameters of the control systems.
