Short summary
A novel bench-scale suspension plant, using magnetorheological elastomer (MRE)-based absorbers accompanied with an adaptive and global neural-network-based tracking controller, is introduced. The global adaptive neural network is used to estimate the uncertain dynamics of the quarter-car model. An auxiliary design system was added to the controller to deal with input constraint effects, and the state was analyzed for its tracking stabilization. All the signals are global, uniform, and ultimate.
