摘要

Integral Discrete-time Sliding Mode Control (IDSMC) for combustion timing and load control of a single cylinder Homogeneous Charge Compression Ignition (HCCI) engine is designed and tested in simulation. First, a Nonlinear Control Oriented Model (NCOM) which is based on measurements is linearized around one operating point and the linearized model is then validated against the NCOM. The linearized model is then combined IDSMC with fueling rate and Exhaust Valve Closing (EVC) used as actuators. The controller is verified in simulation using the NCOM as a virtual engine. The simulation results indicate that IDSMC has acceptable performance for combustion timing and load control in HCCI engine and the performance is superior to classic PI control.
