Dynamic uncertainties and unknown disturbances will degrade the tracking performance of robots. When using a disturber observer-based controller, key to effectively compensate for these is measure or estimate as accurately possible any disturbance. To relax restrictions on design current nonlinear disturbance observer robot, universal proposed higher estimation performance. The stability theore...

In practical applications, for highly nonlinear systems, how to implement control tasks dynamic systems with uncertain parameters is still a hot research issue. Aiming at the internal parameter fluctuations and external unknown disturbances in system, this paper proposes an adaptive terminal sliding mode (ADTSMC) based on finite-time disturbance observer (FTDO) systems. A designed compensate un...

Steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. Moreover, it is an interface between the diver and vehicle. Fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. This paper addresses the fault detection and reconstruction in automotive elect...

In this paper, we are concerned with a cascade of ODE-wave systems with the control actuator-matched disturbance at the boundary of the wave equation. We use the sliding mode control (SMC) technique and the active disturbance rejection control method to overcome the disturbance, respectively. By the SMC approach, the disturbance is supposed to be bounded only. The existence and uniqueness of so...
