Self-tuning Control Based on Discrete Sliding Mode
نویسندگان
چکیده
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.
