چکیده

The extremum seeking controller (ESC) that minimizes the unknown performance index is applied to the control of SI (spark ignition) engines in the idle speed region. The proposed control system consists in the three parts, fuel-jet mount controller, ignition-timing controller and engine speed controller. The ESC applied to the engine speed controller should be modified in order to improve the efficiency of the perturbation signal. Moreover, to decrease the overshoot of the engine speed in starting time, the new control technique of the ignition timing is proposed. Finally to show the effectiveness of the proposal method, the numerical simulations are shown using the mathematical model of a six cylinders SI engine that admission is implemented intermittently.

Extremum Seeking Control With Adaptive Disturbance Feedforward

This paper presents an extension to the classical gradient-based extremum seeking control for the case when the disturbances responsible for changes in the extremum of a selected performance function are available for measurement. Based on these additional measurements, an adaptive extremum seeking disturbance feedforward is designed that approximates the unknown, static mapping between the dis...

Discrete-time extremum-seeking for Wiener-Hammerstein plants

This paper presents a new formulation of extremum-seeking control for discrete-time Wiener– Hammerstein plants. A novel method of analysis using Linear Parameter-Varying (LPV) system theory demonstrates semi-global stability of the control scheme. Assuming only limited plant knowledge, the stability result ensures convergence of the plant output in steady state to a point in an arbitrarily smal...

Unified frameworks for sampled-data extremum seeking control: Global optimisation and multi-unit systems

Two frameworks are proposed for extremum seeking of general nonlinear plants based on a sampled-data control law, within which a broad class of nonlinear programmingmethods is accommodated. It is established that under some generic assumptions, semi-global practical convergence to a global extremum can be achieved. In the case where the extremum seeking algorithm satisfies a stronger asymptotic...

Multidimensional global extremum seeking via the DIRECT optimisation algorithm

DIRECT is a sample-based global optimisation method for Lipschitz continuous functions defined over compact multidimensional domains. This paper adapts the DIRECT method with a modified termination criterion for global extremum seeking control of multivariable dynamical plants. Finite-time semi-global practical convergence is established based on a periodic sampled-data control law, whose sampl...

Air-Fuel Ratio Control of a Lean Burn SI Engine Using Fuzzy Self Tuning Method

Reducing the exhaust emissions of an spark ignition engine by means of engine modifications requires consideration of the effects of these modifications on the variations of crankshaft torque and the engine roughness respectively. Only if the roughness does not exceed a certain level the vehicle do not begin to surge. This paper presents a method for controlling the air-fuel ratio for a lean bu...
