Abstract :
The doublet pulsed feedback system consists of a doublet pulse modulator and a linear position follow-up system. The pulse modulator generates two pulses, an acceleration pulse, and a retarding pulse. The characteristics of the pulses are chosen so that minimum response time and stable operation are achieved. The phase plane method is used to analyze the doublet pulsed system. It is shown that an optimum adaptive contactor servo can be realized using the doublet pulsed system. The validity of approximating higher order transfer functions by a second-order function and an equivalent transportation lag is demonstrated. This enhances the application of the phase plane method to higher order systems. The analytical stipulations are proved experimentally. An experimental procedure to obtain a specified optimization of a high-order pulsed system through the doublet pulser is developed. The switching pattern and the necessary equations to design a doublet pulser are derived.
