The invention discloses a track chassis motion control method, which relates to the technical field of motion control, and comprises the following steps: establishing a kinematic model of a track chassis, analyzing motion characteristics of the track chassis, and determining influence factors; based on the kinematics model, a linear quadratic optimal control algorithm is adopted to perform motion control on the crawler chassis; solving an algebraic Riccati equation, constructing an optimal control law, and calculating to obtain a control quantity; and applying the calculated control quantity to a driving system of the crawler chassis to enable the chassis to move according to an expected path. According to the method, kinematic modeling is carried out on the crawler-type chassis, the kinematic characteristics of the crawler-type chassis are analyzed, and the accuracy of a kinematic model and a control strategy is achieved. By establishing a linearized kinetic model of the crawler chassis and designing an optimal controller by adopting an LQR method, accurate control on the movement of the crawler chassis is realized.
