Sliding Mode Control for Automobile Air Conditioner
نویسندگان
چکیده
Abstract: Increasing demand toward driving comfort steers automobile engineers to spend more and more effort on refining the automobile air conditioning system. The system is of high order and operated at the presence of several disturbances. The control algorithm should be able to control the evaporator out temperature with the acceptable control action. In this work, the sliding mode control is adopted for its advantage of dealing with high order, nonlinear system. Besides, several linear and nonlinear observers are proposed such that the controller may be implemented under the constrain of limited sensor set. Copyright © 2002 IFAC

متن کاملThe Relationship Between Deposit Formation and Oil Leakage of Lip-Type Seal for Automotive Air Conditioner Compressor
Open structure compressor is used for the compressor of automobile air-conditioner due to the drive by engine. This means shaft seal should be necessary for sealing of oil & freon gas of compressor inside. Now, lip type seal with elastic rubber lip and PTFE lip takes the high market share instead of mechanical seal and gains popular favor. More high speed , temperature and pressure are recently...

متن کاملGovernor design for hydropower plants by intelligent sliding mode variable structure control
This work proposes a neural-fuzzy sliding mode control scheme for a hydro-turbine speed governor system. Considering the assumption of elastic water hammer, a nonlinear mode of the hydro-turbine governor system is established. By linearizing this mode, a sliding mode controller is designed. The linearized mode is subject to uncertainties. The uncertainties are generated in the process of linear...
