[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.
[0028] Description of background knowledge:
[0029] Firstly, before introducing the design method of the guidance law for the multi-terminal constrained terminal guidance problem, the concept of inversion design is briefly explained, and the corresponding mathematical description of the inversion design method used in the present invention is given.
[0030] The backstepping inversion design in variable structure control is a regression design method that combines the selection of Lyapunov function with the design of the controller. Its basic idea is to decompose a complex nonlinear system into subsystems that do not exceed the order of the system. By starting from the lowest-order subsystem of the system, the "regression" and "inversion" are designed layer by layer, and finally the global stabilization is achieved. Thus, the control law of the ...
