The gyro stabilized platform control is required to isolate the line of sight (LOS) from the disturbance and vibration of carrier and ensure pointing and tracking for target in electro-optical tracking system. A compound adaptive fuzzy PID control with hysteresis-band switching is developed for this servo system with nonlinear property and some uncertainties. Here, in the adaptive fuzzy controller,...
A dual speed loop cascade control structure using the DC tachometer motor to constitute the inner speed loop, and using the rate gyro to constitute the outer stabilized loop is presented since there is shortcome in single speed loop servo control composed of rate gyro for LOS stabilization in opto-electronic tracking platform system. The functions of reducing inner friction disturbance and bating...
The LOS stabilization control based on gyro stabilized platform is required to isolate the line of sight (LOS) from the movement and vibration of carrier and ensure pointing and tracking for target in electro-optical tracking system. A hybrid adaptive fuzzy PID control is developed for this servo system with nonlinear property and some uncertainties. The self-tuning factors are made to modify the...
This paper presented a novel piezoelectric ceramic-actuated and flexure hinge-based micromanipulator, a compound four-bar parallel configuration was designed to eliminate parasite displacement and decrease concentrated stress, and finite element simulation verified the proposed micromanipulator to be a no parasite displacement and little concentrated one. In addition, a non-linear model based on support...
