Closed loop controller

With its state-of-the-art digital signal processing technology, the NPS3000 series of closed loop controllers combines piezo drive amplifiers, capacitance position sensing circuitry, and servo control capability. Built-in digital algorithms improve settle times and minimize the effects of mechanical resonances. Advanced control techniques allow 21-bit resolution (0.05 nm in 100 ?m). The virtual front panel facilitates user control of all operating parameters, including the PID servo loop setup. Queensgate Instruments Inc., East Meadow, NY; ph 516/357-3900, fax 516/357-9686.
