| Abstract: | The unfalsified control is a control method based on online data. This paper realizes the diversified operations of candidate controllers with the evolution strategy, and combines hysteresis switching algorithm with the switch controllers to achieve the adaptive PID controller. Because of the nonlinear time-varying disturbances in the inertial stabilizing system, we cannot obtain an accurate control model for the controlled object; however, by adopting the unfalsified control algorithm, we can stabilize the inertial stabilizing system with good results such as the azimuth errors less than 3.4 mrad and pitch errors less than 4.36 mard. |
