本文提出了一种基于离散滑模思想的多变量自校正控制方法。在输入输出同维的MIMO框架下，修正了以往基于李雅普诺夫函数的稳定性证明。所提出的方法的性能进行评估，在模拟环境中设计的MBD（基于模型的开发）的汽车系统。给出了汽车V6发动机模型的发动机起动控制的应用。其模型阶数超过50，控制目标是在发动机起动后1.5s内将发动机转速调节到650 ± 50rpm。该控制要求是通过控制发动机转速和进气压力来实现的。
This paper presents a multivariable self-tuning control based on the idea of discrete-time sliding mode. The previous stability proof based on the Lyapunov function is corrected in the MIMO framework that plant input and output have the same dimension. The performance of the proposed method is evaluated in the simulation environment designed for MBD (model based development) of automotive systems. An application to the engine-start control of an automotive V6 engine model is given. Its model order is over 50, and the control objective is to regulate the engine speed at 650 ± 50 rpm within 1.5 s just after the engine starts. This control requirement is achieved by controlling the engine speed and intake pressure with using the proposed multivariable adaptive scheme.
