The stabilization of line of sight against external disturbance is an essential feature of an electromechanical gimbaled sighting system with an optical sensor for sighting. The optimal robust controller based on gap metric is designed to control the rate of the line of sight for an electromechancial target tracking system. It is shown from simulations that the optimal robust controller with the biggest...
Gyro stabilized pod, demanding high tracking precision and stabilization precision, is a nonlinear system. Classical control method is often used in actual system, which is difficult to guarantee high precision and high disturbance rejection ability. According to disturbance characteristics of gyro stabilized pod, this paper presents the active disturbance rejection control (ADRC) algorithm based...
This paper proposes a networked sliding mode controller for servomechanical systems. Asymptotic stability is analyzed. Saturation function is used to eliminate chattering. Sensitivity of the zero eigenvalue with respect to the gain of the saturation function in linear interval is analyzed. Conditions for the choice of the gain and time delay are proposed. Simulations are conducted to verify the theoretical...
The line-of-sight (LOS) stabilization control based on gyro stabilized platform is required to isolate LOS from the movement and vibration of carrier and ensure pointing and tracking for target in electro-optical tracking system. In this paper, a fractional-order PI (FOPI) controller is applied in the design of stabilization loop of LOS stabilization system for the first time, based on the analysis...
