“…The synchronization errors of the two systems are introduced into the magnetic suspension crane tracking system, and the cross-coupling control strategy [44] is determined based on the synchronization errors constructed by the neighbouring order to achieve the synchronization control in two directions respectively. The independent input of the eight single electromagnet systems contained in the magnetic suspension crane tracking system is u = [u i ]…”

The 1/6g environment simulation system is essential in scientific research, exploration, and future space development. The system is technically demanding and must accurately simulate a lowgravity environment while ensuring the reliability and precision of the experiment, which involves complex machinery and control systems that are technically challenging. This paper proposes a new simulation experiment method that combines the traditional hanging low-gravity simulation method and magnetic levitation technology.Realization of the design of the magnetic levitation suspended low gravity simulation system. The magnetically levitated overhead crane, which counteracts 5/6 of the lunar rover's gravity, is the most important component of the entire test system. The article first designs the principle scheme of the magnetically levitated hanging active following a low gravity simulation system, which reduces the influence of the bulky wheel slip structure of the existing equipment on the experiment and improves the system's antiinterference ability. Secondly, the article establishes the dynamics model of the magnetic suspension crane tracking system, analyzes and derives the relationship between the force, the magnetic suspension air gap and the voltage, and lays a theoretical foundation for the smooth operation of the precise control system. Finally, based on the cross-coupling control strategy, the magnetic suspension crane following control system is designed and the cross-coupling control system model is established.
