“…그러나 하드웨어 여유도는 시 스템의 비용과 복잡성 증가, 공간적 제약 등의 문제점으로 인해 많은 제약이 따른다. 이러한 문제점을 극복하기 위한 대안으로써 시스템의 수학적 모델을 기반으로 한 해석적 여 유도(analytic redundancy)를 이용한 신뢰성 확보 방안이 제시 되고 있다 [3][4][5]. 해석적 여유도를 이용한 방법은 제한된 수의 센서와 엑추에이터를 기반으로 시스템의 안정성을 확보하기 위한 기법으로써, 크게 수동적 고장대처기법과 능동적 고장 대처기법으로 나눌 수 있다 [3].…”

“…수동적 기법에서는 주로 강인 제어기를 통해서 제한된 크기의 고장을 외란과 같은 요소로 간주하여 대처하게 된다 [4]. 반면에 능동적 기법의 경우, 고 장에 대한 정확한 검출 및 진단(failure detection and isolation, FDI)을 통하여 고장의 유형을 파악한 후, 이 정보를 이용하 여 고장으로 인해 변경된 시스템의 특성에 적합한 제어기를 실시간으로 재구성(reconfiguration)한다 [5][6][7]. 능동적 방법이 효 과적으로 동작하기 위해서는 고장 검출 및 진단 과정과 제어 기 재구성 과정이 매우 유기적으로 연결되어야 한다.…”

This paper presents a failure diagnosis and accommodation strategy which is capable of tolerating faulty actuators of a submersible vehicle. The proposed method is mainly based on a sliding mode control technique. The primary ideas include a performance index to describe the effectiveness of actuators, and a controller reconfiguration strategy using the actuator effectiveness index. The actuator effectiveness proposed in this work is defined as the relationship between the sliding surface and the controlled system behavior. The resulting actuator effectiveness is then used in reconfiguring the controller in order to counteract for the deteriorated control performance in the presence of a faulty actuator. The effectiveness of the proposed method is demonstrated by means of numerical simulations with a submersible vehicle.

“…[5][6][7][8][9] Applying a sliding mode control (SMC) may cause an undesirable high-frequency input, which is so called 'chattering 10) phenomena'. A high-order sliding mode (HOSM), 8,[11][12][13] which includes a second-order sliding mode (SOSM) used in this study, mitigates the chatter problems associated with SMC.…”

This paper focuses on autonomous path-following flight taking uncertainty and external disturbances into account. Integrated guidance and autopilot are developed using a second-order sliding mode approach that is one of the well-known approaches for mitigating so-called 'chattering phenomena'. The input magnitude for such a higher-order sliding mode approach tends to be extremely large in the initial reaching phase. In this paper, a novel sliding surface is developed using Ackermann and Utkin's method for reaching the surface smoothly to attenuate such extremely large initial inputs along with uncertainty and disturbance compensation. The potential of the proposed methodology is demonstrated with some path-following application under wind turbulence. Performance comparison with a conventional higher-order sliding mode approach is also presented.

SUMMARYAsymptotic output tracking in a class of causal nonminimum-phase uncertain nonlinear systems is addressed via higher-order sliding modes (HOSMs). Local asymptotic stability of the output-tracking error dynamics is provided. An output reference profile and an external disturbance forcing the internal dynamics are defined by an unknown linear exosystem. Its characteristic polynomial (which is used in the output-tracking control algorithm) is identified online by using a HOSM parameter observer. A numerical example illustrates efficiency of the developed HOSM control algorithm.
