Book excerpt: Abstract: The air-fuel ratio control problem has been the focus of research in academia ever since the advent of microprocessor based control of automotive systems. With rising fuel costs, increased environmental consciousness, and the need to be competitive in the global market, automotive manufacturers, who have traditionally relied on extensive experimental calibration to fine tune performance, are moving towardsmodel based calibration of control gains to minimize costs and incorporate advances in power-train technology in a systematic manner. While solutions presented in the open literature to date illustrate the application of the plethora of modern control theory to this problem, calibration effort and emissions performance have not been given adequate priority. The work presented in this document bridges a gap between academia and industry by using modern advances in control theory to design a solution that significantly minimizes the calibration effort required to meet performance requirements. Through proper design of experiments, data collected from the plant is used to design mathematical models that represent the dominant dynamics observed in the intake system, the fueling, combustion and gas transport and finally the behavior of the three way catalyst. The structure of these models are chosen by a deep understanding of the physics involved. System identification is used to simplify the model structure. To capture the highly nonlinear operating condition based behavior of the plant, a linear parameter varying approach is used to schedule the model coefficients through the use of linear splines on manifold pressure, engine speed and coolant temperature. The control architecture chosen utilizes a servomechanism incorporating coordinated open and closed loop control action to meet the desired performance goal and is universal in the sense that both switching sensor and linear sensor based systems can be easily accommodated with minimal change. A rapid action inner-loop, with the pre-catalyst oxygen sensor feedback to control the engine exhaust, is used in conjunction with an outer loop with post catalyst oxygen sensor feedback, to control the oxygen storage in the catalyst. Calibration of the control gains is achieved through closed loop optimization using genetic algorithms. Parallel computing is used for this optimization. Performance and stability criteria are simultaneously incorporated in the cost function to achieve the desired goals. Numerical linear matrix inequality based tests are used to guarantee stability of the closed loop system over the entire operating region. Although the discussion in this dissertation is restricted to calibration of the inner-loop compensator, one can easily adopt the proposed techniques for the design of the outer-loop compensator, as well as for a wide variety of feedback control systems.
Book Synopsis Introduction to Modeling and Control of Internal Combustion Engine Systems by : Lino Guzzella
Download or read book Introduction to Modeling and Control of Internal Combustion Engine Systems written by Lino Guzzella and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internal combustion engines still have a potential for substantial improvements, particularly with regard to fuel efficiency and environmental compatibility. These goals can be achieved with help of control systems. Modeling and Control of Internal Combustion Engines (ICE) addresses these issues by offering an introduction to cost-effective model-based control system design for ICE. The primary emphasis is put on the ICE and its auxiliary devices. Mathematical models for these processes are developed in the text and selected feedforward and feedback control problems are discussed. The appendix contains a summary of the most important controller analysis and design methods, and a case study that analyzes a simplified idle-speed control problem. The book is written for students interested in the design of classical and novel ICE control systems.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The latest emission regulations demand drastic reduction of tailpipe hydrocarbon emission of Spark Ignited, Port Fuel Injected (SI PFI) automotive engines during crank-to-run transition. This results in sharply increased calibration effort and associated cost based on the current control architecture of production engines, during this extremely fast transient operating regime under the constraints of substantial emission reduction and good engine startability. A new approach using model based control is proposed for this problem. The engine start behavior and overall fuel dynamics characterization during crank-to-run transition are thoroughly investigated. A scheduled in-cylinder fresh air charge predictor is constructed. A nonlinear input correction function, invoked prior to engaging fuel dynamics control, is developed. In order to cover a wide range of engine coolant temperatures by means of scheduling, the linear spline modeling technique is applied to air and fuel dynamics modeling, identification and control design. A new criteria, from the class of subspace methods, is introduced to evaluate system order and model quality. Finally, a predictive fuel dynamics control scheme is realized to overcome individual cylinder fuel dynamics effect by systematically combining the scheduled in-cylinder fresh air charge predictor, the direct inversion of a fuel dynamics model and an inverse correction function. By means of an intelligent mode scheduling of the in-cylinder fresh air charge predictor with misfire and poor-start detection, a fault tolerant predictive fuel dynamics control results. It has been demonstrated that the calibration effort of start fuel control during engine start and crank-to-run transition is reduced significantly for production inline-4 cylinder engines. In addition to solving this practical problem using model based control, this dissertation research also raises several theoretical questions worthy of further research. In summary, this dissertation research makes following contributions: 1) individual in-cylinder fresh air charge prediction and individual cylinder fuel dynamics compensation; 2) accommodated misfire and poor-start; 3) significantly reduced calibration effort; 4) introduction of the Linear Parameter Varying Linear Splines (LPV-LSP) technique for gain scheduled modeling, identification and control design; and 5) introduction of a novel method to identify ARMA models using subspace methods.
