Oscillators are not typically used in automatic control systems. Their main function is to generate repetitive signals, which doesn't align with the primary functions of control systems such as error detection, measurement, and control action execution. Control systems usually consist of sensors to measure the process variable, error detectors to compare the measured value with a set point, and final control elements to adjust the process.
