In a high-precision servo system, the nonlinear friction link is key factor affecting system performance. Reasonable solving of in systems has become focus current research. This paper summarizes nonlinearity that affects control performance systems. First, characteristics are summarized, and advantages disadvantages typical models recent years analyzed. Subsequently, existing model parameter i...

This research aims at developing control law strategies that improve the performances and robustness of electrohydraulic servosystems (EHSS) operation while considering easy implementation. To address strongly nonlinear nature EHSS, a number algorithms based on backstepping approach is intensively used in literature. The main contribution this paper to consider an alternative synthetize Lyapuno...
