Carrier rocket attitude control method considering time domain and frequency domain characteristics

The invention is suitable for the technical field of aircraft control, and provides a carrier rocket attitude control method considering time domain and frequency domain characteristics. The method comprises the following steps: constructing an attitude motion model and an attitude error state space equation of the carrier rocket; designing a preset performance function meeting a time domain characteristic requirement, and converting the attitude error state-space equation into an unconstrained system through homeomorphic mapping; linearizing the unconstrained system based on a small disturbance method; designing a PD control law according to the obtained linear unconstrained system, calculating an open-loop transfer function, drawing a corresponding Bode diagram, and obtaining PD control parameters meeting frequency domain characteristic requirements by adjusting proportional gain and differential gain; and controlling the attitude of the carrier rocket according to the obtained PD control law and the contro
