This paper proposes new methodologies for the design of adaptive sliding mode control. The goal is to obtain a robust sliding mode adaptive gain control law with respect to uncertainties and perturbations without the knowledge of uncertainties/perturbations bound (only the boundness feature is known). The proposed approaches consist in having a dynamical adaptive control gain that establishes a sliding mode in finite time.. Gain dynamics ensures also that there is no over-estimation of the gain with respect to the real a priori unknown value of uncertainties. The efficacy of both proposed algorithms is confirmed on a tutorial example and while controlling an electropneumatic actuator.

“…Hence, the convergence cannot be easily made arbitrarily fast or slow. The approach given in [16] combines SMC with linear quadratic one. In spite of several advantages (constructive approach, practical applicability), this approach suffers of a major drawback: the higher order sliding mode is only practical, i.e.…”

A higher order sliding mode control algorithm is proposed for a class of uncertain multi-input multi-output nonlinear systems. This problem can be viewed as the finite time stabilization of a higher order input-output dynamic system with bounded uncertainties. The developed control scheme is based on geometric homogeneity and sliding mode control. The proposed procedure provides explicit conditions on the controller parameters and guarantees robustness against uncertainties. An illustrative example of a hovercraft vessel control demonstrates the advantages of the strategy.

“…Now, the results of Backstepping controller defined by (16) are presented with using only the ARD for recover the velocity and the acceleration signal. In this case, using the classical scheme is impossible since the velocity and the acceleration gains are respectively about 20 and 10 which amplifies enormously chattering effect.…”

“…Some of those algorithms are based on the technique of sliding modes. This technique is mostly used to elaborate the control laws [5], [16], [19]. The main features of the sliding modes control are its robustness to variation in system parameters, external disturbances and modelling errors, [27].…”

Abstract:In general, feedback controllers require measurements of velocity and acceleration for feedback. To avoid the complexity of overall system with minimizing the sensor number implements on a test bench, a new estimation algorithm of the successive derivatives of measured signal is proposed. The differentiator design is a very difficult task because the important problem in real time differentiation signal is to combine differentiation exactness with robustness in respect of measurements errors and input noises. For this target, a higher order sliding modes differentiator with dynamic gains is proposed. The experimental validation highlights the performances of the differentiator/controller design of a high dynamic electrohydraulic servo-system. For this validation, two controllers are implemented on the test bench for position tracking objective. Moreover, two kinds of differentiators are also tested: the proposed one and some classic algorithm.
