Examples in Context
- Elevation servo power amplifier
- In high precision DC servo system, the PWM power amplifier based on power electronic devices is mainly used.
- This paper introduces the composition of electro-hydraulic servo control system. Especially, the triangular wave generator, PWM principle and the power amplifier stage circuit in the servo amplifier are described. Finally, the frequency response of servo valve to the PWM driving signal is analysed.
- A spaceborne angular velocity servo system for electro-optical tracking of space targets is designed, which consists of a compensator, a driver and a power amplifier, a mechanical assembly to control optical telescope and tracking gimbal and the LOS stabilization loop.
- If the efficiency of servo amplifier is considered, it is practicable that the power supply voltage is about 3 times as large as the servo amplifier output voltage corresponding to rated current.
