In this work, an adaptive integral sliding mode control (AISMC) is proposed for the purpose of regulating the ICE air path. The main contribution of this paper is the combination of the traditional SMC with an adaptive gain mechanism coupled with an integral action in the definition of the sliding surface. The simulation results show the ability of the proposed controller to achieve fault tolerant performance against parametric uncertainties and actuator faults. © 2014 IEEE.

This paper investigates second order sliding mode control. The use of the super twisting algorithm for the combustion engine air path is to achieve fault-tolerance and to enhance the chattering phenomenon. Comparing to the adaptive sliding mode controller (ASMC), the obtained results showed good performances for actuator fault-accommodation even in the presence of uncertainties on model parameters. © 2013 IEEE.

In this paper we present a passive fault tolerant control strategy for the Internal Combustion air path. This strategy is carried out under the concept of Higher Order Sliding Mode Control (HOSMC). The proposed fault tolerant strategy incorporates a Super-Twisting controller which handles parametric uncertainties and actuator failures. In this paper we consider two types of actuator failures, additive and loss-of-effectiveness faults., theoretical results on the convergence of the proposed controller based on the Lyapunov theory are derived. The simulations of the proposed controller on a recently validated experimental air path internal combustion model, show good results for actuator failures conditions even in the presence of uncertainties on model parameters. © 2014 IEEE.

In this paper, a Sampled Data Disturbance Observer (SDDOB) which estimates simultaneously the unmeasurable states and the uncertainties for the EHA systems is presented. The novelty of our approach is the use of an inter-sample output predictor which allow the users to increase the frequency acquisition of the piston position sensor without affecting the convergence performance. The stability analyses of the proposed observer is proved using Lyapunov function adapted to hybrid systems. To show the efficiency of the SDDOB, numerical simulations of a control application which combines the SDDOB and a PI controller for the purpose of piston position tracking problem is presented. © 2015 American Automatic Control Council.

In this paper, a time varying disturbance observer subject to sampled data's measurements is proposed for a class of non-linear systems. The proposed observer combines the advantage of a high gain structure in terms of convergence speed and an output predictor which remains continuous between the sampling times. The exponential convergence of the proposed observer is proved using a Lyapunov function adapted to impulsive systems. © IFAC.

For modern Diesel engines, accurate fuel-air ratio AFR and Exhaust Gas Recirculation (EGR) rates control is important for manufacturers to face a more restrictive legislation levels. To fulfill the requirements, hardware devices such (EGR) and Variable Geometry Turbochargers (VGT) valves have been introduced, and sophisticated control algorithms were designed. The main objective of the air path controller is to regulate in the intake manifold the AFR ratio and the EGR fraction rates to their desired values. Earlier EGR PID controllers needed a fastidious and time consuming calibration step for each engine operating point. Nonlinear control algorithms has quickly appeared as a promising way to provide an efficient air path controllers, since they don't need a calibration step. The main drawback of such controllers is coming from the fact that they are based upon a diesel engine model which handles parameters uncertainties and signal measurements errors, that affects the control performance. In this paper we propose a novel control scheme for controlling the diesel engine air path. Control design is carried out under the sliding mode framework. The proposed controller has been tested on the Jankovic Tubocharged Diesel Engine (TDE) model. To demonstrate the robustness of the proposed controller, simulation results showing the tracking of the compressor flow W c and the exhaust manifold pressure p 2 variables are presented. © 2012 IEEE.

The automotive industry faces actually new challenges, due to a more stringent exhaust emissions legislation. Pressure to lower emissions while maintaining or improving other engine performance parameters required, that the intake air properties be better controlled and matched at every engine operating conditions. In this paper we developed a robust sliding mode controller for the diesel engine air path. The proposed controller incorporates an adaptive switching gain which avoids knowing uncertainties bounds caused by model parametric variations or and external disturbances. Stability analysis of the closed loop scheme have been proved using the Lyapunov theory,. The proposed controller has been tested on the Jankovic Tubocharged Diesel Engine (TDE) model air path.simulations results demonstrates the robustness of the controller facing unmodelled dynamic and actuator fault leakage. © 2012 Institute of Engineers.

This paper develops a sliding mode controller via nonlinear disturbance observer for diesel generator system subject to matched and unmatched disturbances. The proposed controller is based upon a novel nonlinear disturbance observer structure which uses the concept of total disturbance estimation in order to estimate simultaneously the matched and the unmatched disturbances in the system. This estimation is incorporated then in a composite observer based controller where the Lyapunov based stability analysis is given. Simulations results illustrate the effectiveness of the proposed controller compared to the baseline sliding mode controller and shows its advantages in terms of disturbance rejection, chattering reduction and nominal performance recovery. © 2015 IEEE.
