High-performance feedback controllers: SISO and MIMO,
digital and analog, for electrical and mechanical plants
Design experience:
The following controllers are among those designed by B.
Lurie at the Jet Propulsion Laboratory:
- Position controller for the retroreflector carriage and several antennas
controllers of the Chemistry Spacecraft. All these controllers are
high-order and nonlinear, they control plants with structural modes, and
include a high-order linear part with a Bode step.
- A nonlinear digital controller for Mars Pathfinder high-gain antenna
pointing to Earth.
- Switched-capacitor controller for STRV spacecraft cryogenic cooler
vibration rejection.
- Vibration damping in the model of space stellar interferometer.
- Microgravity accelerometer analog feedback loop (nonlinear, fast, with
Angstrom accuracy).
- Cassini: Narrow View Camera thermal control, Mapping Spectrometer X-Y
attitude controller, Computer clock PLL for the radar (frequency and duty
cycle control).
- High-voltage power source for Deep Space Network klystron radar.
- A feedback-feedforward digital attitude controller for DS-1 spacecraft
solar panels.
- Stellar Interferometer optical delay line control (main-vernier, with nm
accuracy).
- Transmitter/receiver pointing system for space optical telecommunications.
