Abstract :
A frequency-pumped controller (FPC) is presented that processes the position servomechanism by the frequency-locked technique. With the proposed FPC, a position/voltage (P/V) transducer, and a voltage-controlled oscillator (VCO), a frequency-locked position servo (FLPS) control system is established. Mathematical models for the FPC and for the FLPS are constructed, and their stability criteria for in-lock and for out-of-lock cases, respectively, are derived. Computer simulation and experimental results confirm the theoretical prediction that the proposed FLPS can provide real-time control, good stability, higher resolution, and higher precision
