This paper deals with the soft landing of the lunar lander. The design of the controller and guidance law has been completed in two steps. At first, utilizing a differential homeomorphic transformation and a nonlinear input compensation, we transform the dynamics description of the lunar lander into a linear system. Then, based on the Yula equation of the classic optimal control method, a designing procedure and the general explicit solution of the normal guidance law is given. In the second steps, making use of H/sub /spl infin//control approach, we design a feedback controller for the uncertainties and disturbance such that the real system can track the normal orbit. At last, simulation results illustrate the feasibility and advantage of our approach.
