多星接管目标的分布式近似最优姿态跟踪控制
Distributed Approximate Optimal Attitude Tracking Control for Taking Over the Target by Multiple Satellites
摘要
Abstract
In the on-orbit service missions of attitude takeover control of the failed spacecraft by multiple service satellites,a distributed attitude tracking takeover control policy is proposed based on the method of adaptive dy-namic programming(ADP)with unknown inertia matrix and actuator saturation.Firstly,by modeling and analyz-ing the attitude system,a value function with torque saturation constraint and desired torque compensation is de-signed.Under the ADP framework,a set of basis functions is used to approximate the optimal value function,and the distributed approximate optimal attitude tracking control strategy is obtained;Then,the filtered linear regres-sion models relevant to inertia parameters and weight parameters are respectively established with angular accelera-tion information free and according to concurrent learning method,parameter consensus algorithm and off-policy trajectories,the adaptive inertia parameter identification law and the weight update law are designed;Furthermore,the uniformly ultimate boundedness of the attitude tracking errors,the inertia matrix identification errors and weight parameter estimation errors are proved by Lyapunov method;Finally,the simulation results verify the ef-fectiveness of the distributed attitude tracking control method for attitude tracking and inertia matrix identifica-tion under the constraint of torque saturation.关键词
