Robust Passive Fault Tolerant Control for Air Fuel Ratio Control of Internal Combustion Gasoline Engine for Sensor and Actuator Faults

Arslan Ahmed Amin et al.

Summary: This paper presents a novel Passive Fault Tolerant Control System (PFTCS) for Air Fuel Ratio (AFR) control system of the Internal Combustion (IC) gasoline engine to prevent its shutdown. The system uses a Proportional plus Integral (PI) controller to control AFR by introducing a fuel throttle valve, and it has a simple structure and high robustness. The reliability and robustness of the system are verified through dual redundancy in hardware and introducing noise in sensor measurements.

Unified Fault-Tolerant Control for Air-Fuel Ratio Control of Internal Combustion Engines with Advanced Analytical and Hardware Redundancies

Arslan Ahmed Amin et al.

Summary: This paper introduces a Unified Fault-Tolerant Control System (UFTCS) for Air-Fuel Ratio control in Spark Ignition Internal Combustion engines, utilizing advanced analytical redundancies and hardware redundancies. The system comprises a Hybrid Fault-Tolerant Control System (HFTCS) and hardware redundancy protocols like Modified Triple Modular Redundancy (MTMR) for sensors and Dual Redundancy (DR) for actuators to enhance the overall reliability and robustness of the control system.
