Fault-tolerant control based Super-Twisting algorithm for the diesel engine air path subject to loss-of-effectiveness and additive actuator faults

Abstract

In this paper, a passive fault tolerant control strategy carried out under the concept of higher order sliding mode control is developed for the diesel engine air path. The proposed fault tolerant strategy incorporates a Super-Twisting algorithm controller which handles parametric uncertainties and actuator faults. In this paper we consider two types of actuator faults, additive and loss-of-effectiveness faults. Theoretical results on the convergence of the proposed controller based on the Lyapunov theory are presented. The simulations of the proposed controller on a recently validated experimental air path diesel engine model show good results under actuator faults conditions even in the presence of parametric uncertainties.

Adaptive integral sliding mode fault‐tolerant control for diesel engine air path system via disturbance observer

“…For diesel engines, the change of T 1 and T 2 is usually very slow, so the model parameters (k 1 , k 2 , k c , k e , k t ) are usually taken as constants. [17][18][19][20][21]33 In order to facilitate the design of the controller in this article, according to the literature, 19 the TA B L E 1 Meaning of diesel engine variables in this paper.…”

“…The presence of these adverse conditions can lead to deviations between the diesel engine model and the actual system, resulting in reduced control effectiveness, or even loss of control. To enhance the reliability of the DEAP system, fault‐tolerant control algorithms specifically designed for this system have emerged 17–21 . In Reference 17, the super‐twisting algorithm is used to address the situation where both additive faults and loss of effectiveness (LOE) faults coexist in the DEAP system.…”

[17][18][19][20][21] In Reference 17, the super-twisting algorithm is used to address the situation where both additive faults and loss of effectiveness (LOE) faults coexist in the DEAP system. Similarly, in Reference 18, the combination of an extended state observer and the super-twisting algorithm is employed to achieve precise tracking of the desired state in the presence of similar fault scenarios.…”

“…This controller has a relatively simple structure but is capable of simultaneously handling external matched and mismatched disturbances, as well as additive and LOE faults in the system. To the best of our knowledge, [17][18][19][20][21] this is the first controller designed specifically for DEAP systems that can address the simultaneous occurrence of the aforementioned conditions. 2.…”

Actuator Fault Tolerant Control of Variable Cycle Engine Using Sliding Mode Control Scheme

“…The sliding mode control (SMC) theory attracts much attention for its simple control structure and good performance in dealing with various uncertainties. Ahmed Ali et al [16] use the Super-Twisting algorithm, which is a higher-order SMC, to handle the additive and loss-ofeffectiveness actuator faults for diesel engine air path. Trinh et al [17] propose a fault estimation and fault-tolerant control strategy with two observers for a pump-controlled electrohydraulic system (PCEHS) under the presence of internal leakage faults and an external In terms of actuator FTC design for aircraft engines, there are only a few pieces of research that address the diagnosis approaches [9,10] of the actuator faults.…”
