本篇文章中，利用非線性交互項回前之技術設計控制器來控制均質進氣壓燃(Homogeneous Charge Compression Ignition, HCCI)引擎。控制目標為不同的燃油注入量時，仍能維持燃油燃燒時間點(CA50)。為了進行以模型為基礎之控制器設計，一個單缸HCCI引擎之高階模型將先被簡化，而簡化的模型將以里亞普諾夫函式(Lyapunov function)為基礎進行非線性控制器的設計。另外，由於實際情形下，HCCI引擎系統中存在難以量測的狀態變數，例如閥門關閉時的缸內溫度，故在此亦對該狀態變數設計估測器。研究中所設計之交互項控制器在與高階模型建構之閉迴路模擬表現亦顯現出其具有一定程度的強健性。

In this thesis, a nonlinear controller for homogeneous charge compression ignition (HCCI) engines is developed based on cross-term forwarding control techniques. The control goal is to maintain the combustion timing of 50% fuel burned during fuel step changes. In order to design a model-based controller, a reduced order model is first developed. The simplified model is used to develop a nonlinear controller based on a Lyapunov function. State variables such as temperature in the cylinder at valve closing are either difficult or impossible to measure. An observer for the temperature in the cylinder at valve closing is designed in order to implement the feedback control. Finally, the controller is implemented on a high-order model. The simulation results show that the closed-loop system is robust to a variety of model uncertainties and measurement noise.
