In order to apply the sliding mode control to a remotely operated vehicle (ROV), prior knowledge of exact bounds for parameter uncertainties and external disturbances is a prerequisite. However, these bounds may not be easily obtained because of the complexity and unpredictability of the structure of uncertainties in the dynamics of ROVs. In order to overcome such a difficulty in the control of...

This paper proposes a second-order nonsingular terminal sliding mode decomposed control method for multivariable linear systems with internal parameter uncertainties and external disturbances. First, the systems are converted into the block controllable form, consisting of an input-output subsystem and a stable internal dynamic subsystem. A special second-order nonsingular terminal sliding mode...

Using the concept of dynamic sliding mode control, an asymptotic robust controller for high order nonlinear systems is presented. In this approach, a n-order nonlinear system is transformed into a first order system through systematic backstepping design and then it will be shown that the control objective is equivalent to design a robust control law for a 2 order auxiliary system with only out...

This paper presents a novel fuzzy logic based Adaptive Super-twisting Sliding Mode Controller for the control of dynamic uncertain systems. The proposed controller combines the advantages of Second order Sliding Mode Control, Fuzzy Logic Control and Adaptive Control. The reaching conditions, stability and robustness of the system with the proposed controller are guaranteed. In addition, the pro...

A continuous nonsingular terminal sliding mode control approach is proposed for mismatched disturbance attenuation. A novel nonlinear dynamic sliding mode surface is designed based on a finite-time disturbance observer. The time taken to reach the desired setpoint from any initial states under mismatched disturbance is guaranteed to be finite time. In addition, the proposed method exhibits the ...

Being a motion on a discontinuity set of a dynamic system, sliding mode is used to keep accurately a given constraint and features theoretically-infinite-frequency switching. Standard sliding modes provide for finite-time convergence, precise keeping of the constraint and robustness with respect to internal and external disturbances. Yet the relative degree of the constraint has to be 1 and a d...

This paper presents the design of an optimal nonlinear controller for trajectory tracking of a quadrotor helicopter based on the well-known sliding mode control method (SMC). To this end, the Lyapunov law analysis has been used regarding nonlinear equations of the quadrotor. The proposed control method is characterized by its robustness against disturbances and aerodynamic effects. One of the m...
