Control law for decentralized variable structure model reference adaptive controller for Chinese space station

For the control law for decentralized variable structure model reference adaptive controller for space station, which is a large flexible space structure, with the theoretical papers using the decentralized variable structure control approach, a control law for controller was deduced. The mathematical model of space station is transformed into four interconnected subsystems. Each of the four subsystems has a local reference model. The decentralized control law for the four subsystems is given. The symbols are explained. The decentralized control law can guarantee the stability and safe operation of the space station under high dynamical disturbances and when system parameters vary within broad ranges. The decentralized control law is simple for realtime implementation, and its effectiveness is demonstrated by numerical simulations.
