- Abstract
In the unmanned aerial vehicle control system design, the controller design is the base of improving the control stability performance, considering the nonlinear and uncertain properties of the model, the beam space weighted spectral peak searching method is used to estimate the unknown parameters of the object. In the control system, when the pulse frequency becomes higher, signal DC component coupling capacitor will drift to the zero level, which produces baseline drift. This paper presents an UAV flight control system design optimization method based on baseline drift suppression. Using a self buffer DC baseline restorer to reduce the time constant of the discharge circuit, accelerates the discharge process, improves the control performance, and prevents baseline drift. The overall design description of UAV flight control system is analyzed, function and parameters are presented, and the hardware module of control system is designed. The performance of the system is tested by simulation. The simulation results show that, the control system can effectively inhibit the baseline drift of UAV flight control system, it has high control precision, the UAV pitch angle, and rudder angle have better tracking performance.
