The invention relates to a Lorentz force magnetic suspension universal gravity unloading method. Aiming at a Lorentz force universal stable platform ground demonstration device, a magnetic suspension carrier universal gravity unloading method is researched, a Lorentz force magnetic suspension gravity unloading principle is analyzed, Lorentz force magnetic bearing magnetic force influence factors are clarified based on an equivalent magnetic circuit method and a magnetic circuit Ohm law, a Lorentz force magnetic suspension universal gravity unloading kinetic model is deduced, and a Lorentz force magnetic suspension universal gravity unloading model is obtained. A magnetic suspension carrier gravity center shift state observer is designed, on the basis, a magnetic suspension carrier motion internal model control law based on the gravity center shift observer is constructed, and then stable suspension of the magnetic suspension carrier under six degrees of freedom is achieved so as to simulate a space weightless environment. Therefore, the whole machine function and performance of the Lorentz force magnetic suspension universal stabilized platform can be tested on the ground.
