ANALYSIS OF OPTIMALIZING CONTROL SYSTEMS UNDER RANDOM INTERFERENCE,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Two types of optimalizing control systems are analyzed and compared 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 steadystate 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 optimalizing system has smaller hunting losses. The calculation results give us the best step length for the gradient-type optimalizing system and the best hunting amplitude for the correlation-type optimalizing system for various noise levels. These results are important parameters of the control systems. Author
