“…Because 307 the advantages of the super-twisting SMDO illustrated as follows, the super-twisting SMDO is introduced to estimate 308 the disturbance in the fast-loop and corresponding compensation control law is derived in this section. a) As one of the 309 second order sliding mode control algorithms, it can avoid the chattering problem of a first order sliding mode control, 310 and also inherits the advantages of the latter (Huang et al 2015). b) Since the super-twisting algorithm contains a 311 discontinuous function under the integral, chattering can be attenuated (Pico et al 2013).…”

Uncertainty and external disturbance during Mars entry process inevitably degrade the performance of Mars 5 entry guidance and control algorithms. Traditional approaches focus on suppressing disturbances and compensating 6 uncertainties, which usually results in larger control responses beyond the limited control capability of Mars entry 7vehicle. This paper further takes the limited actuator ability into consideration, and proposes the Mars entry robust 8 attitude control strategy using the terminal sliding mode control (TSMC) with anti-windup (AW) and super-twisting 9 sliding mode disturbance observer (SMDO). First, terminal sliding mode control with anti-windup is developed to 10 robustly track the nominal attitude command under uncertainty and limited control capability. Then, the super-twisting 11 sliding mode disturbance observer is introduced to online estimate the disturbances and further enhance the attitude 12 control accuracy and robustness. Finally, the comparison simulation results illustrate that the proposed control strategy 13 not only performs well in tracking the reference commands even in the presence of uncertain disturbance but also avoids 14 control saturation issue. 15 16

This paper presents a novel adaptive sliding-mode control (ASMC) method for Mars entry guidance and the finite-time convergence in the presence of large uncertainties can be guaranteed. With the help of gain adaptive law, the nonoverestimating value of control gains can be achieved, and then, the chattering can be attenuated by the proposed ASMC method. Meanwhile, the extended state observer is introduced to estimate and compensate for uncertainties and the nonoverestimating problem is resolved further. In addition, the proposed method does not require any knowledge on the upper bound of uncertainty, which yields to be used in practical systems. Finally, the numerical simulation results are given to demonstrate the effectiveness of the proposed guidance law.

“…Currently, there are different observers that exhibit some degree of robustness and can be applied to linear and nonlinear systems. Because the observers design problem is related to the controllers design problem, different robust control techniques have been used to design robust observers; see, for example, [4][5][6][7][8]. Particularly, the observers based on sliding mode technique have shown good convergence properties and exhibit good performance to external bounded disturbances.…”

A procedure to design an asymptotically stable second-order sliding mode observer for a class of single input single output (SISO) nonlinear systems in normal form is presented. The observer converges to the system state in spite of the existence of bounded disturbances and parameter uncertainties affecting the system dynamics. At the same time, the observer estimates the disturbances without the use of an additional filter to recover the equivalent control. The observer design is modular; each module of the observer is applied to each equation of state of the plant. Because of this, the proposed observer can be applied to a broader class of dynamic systems. The performance of the observer is illustrated in numerical and experimental form.
