Parameter Optimization on FNN/PID Compound Controller for a Three-Axis Inertially Stabilized Platform for Aerial Remote Sensing Applications

Table 2

The numerical results on the stabilization precision obtained three different methods responding to the step input.

Control methods	0–30s	Improvement (%) FFN/PID vs. PID	Improvement (%) FFN/PID with optimized parameters vs. FFN/PID with unoptimized parameters
PID/RMS (°)	0.0931	—	—
FFN/PID based on trial and error method/RMS (°)	0.0432	53.6	—
FFN/PID based on composite parameter optimization method/RMS (°)	0.0214	77.0	50.5
