Sliding mode controller for internal combustion engine for energy-efficient operation of hybrid electric vehicles

Abstract: This paper presents a new concept with different control strategies. The developed intelligent speed controller utilises a gear box which includes a gear train with two inputs, one coupled with the engine shaft and another with the shaft of a variable speed controlled motor. The net output speed is a combination of the two input speeds and is governed by the transmission ratio of the planetary gear train. This new approach eliminates the use of a torque converter, which reduces the power loss that occurs in the box during fluid coupling. By gradually varying the speed of the induction motor a stepless transmission is achieved. The developed controller also scores in climbing a step gradient and reversing the vehicle, by intelligent mixing of the induction motor and engine speeds. This approach eliminates the traditional braking system in the entire vehicle design. The use of two power sources, IC engine and battery-driven induction motor, utilises the modern idea of hybrid vehicles. The new speed controller is capable of driving a vehicle even in an extreme case of IC engine failure, during gas depletion and for plausibility errors.
