LVDT-Servo is a turnkey instrument combining Innovative’s Cardsharp single board computer, FMC-Servo I/O module plus custom firmware and software to perform 4 channels of LVDT synchronous, simultaneous demodulation and control.
The digital demodulation core provides sharp digital low-pass filtering and rapid phase tracking on the delta phase of the excitation and return signal. Built-in null point calibration efficiently solves the offset error around the null point. The powerful hardware platform supports a wide range of excitation frequencies from 400 Hz to 20 KHz, with latency of less than 2.7 ms.
The Xilinx Zynq Z7045 FPGA is available for custom, real-time servo loop core implementations. Build the algorithm in VHDL, Xilinx System Generator and MATLAB, or Xilinx High Level Synthesizer (HLS) running inside the FPGA. Then, run a C++ program as the servo loop running in bare-metal in CPU core 1.
Synchronize to an unlimited number of LVDT-Servo signal conditioners by applying the same external clock and external trigger to the FMC-Servo front panel connector.
