串联式混合动力汽车模糊控制策略的研究

段建民,吴艳苹,刘旭东(,100022):针对串联式混合动力汽车特点,提出了恒SOC模糊逻辑控制策略一方面,模糊逻辑控制器根据路况功率需求和蓄电池SOC,分配发动机给定功率,实现恒SOC控制;另一方面,将发动机的工作点控制在发动机最小燃油消耗的高效率区间内,使发动机具有较好的燃油经济性实例仿真结果表明,恒SOC模糊逻辑控制具有较好的鲁棒性,能在不同的循环工况下实现恒SOC控制,且具有较好的燃油经济性:;SOC;:U469.72:A:1006-0006(2009)01-0028-03StudyonFuzzyLogicControlStrategyforSeriesHybridElectricVehicleDUANJianmin,WUYanping,LIUXudong(CollegeofElectronicInformationandControlEngineering,BeijingUniversityofTechnology,Beijing100022,China)Abstrac:tAccordingtothecharacteristicsofserieshybridelectricvehicle,theconstantSOCfuzzylogiccontrolisproposed.BasedonthepowerrequestandSOC,thefuzzylogiccontrollercandistributetheenginegivenpowertorealizeconstantSOCcontro.lFurthermore,theengineoperatingpointsarecontrolledonoptimalfuelconsumptioncurve.ThestudiesoncaseprovethatthefuzzylogiccontrollercanrealizetheconstantSOCcontrolunderdifferentroadconditions,sothatithasthewellrobustness.Keywords:Serieshybridelectricvehicle;ConstantSOCcontro;lFuzzylogiccontrol,,[1],,,HEV,;,,,,,[2~4],,(SeriesHybridElectricVehicle,SHEV),(StateofCharge,SOC),11.1,,,,1,1Fig.1StructureofSHEV,1.2SOCSOC,SHEV,,,SOCSOC,SOC:,,;,SOC,,SOC,,,Uboc/Rchg/RdisSOC2,,SOC0.7,,,SOC0.7,,SOCcs_hi_soc=0.9cs_lo_soc=0.5SOC;SOC;SOC2Fig.2OpenCircuitVoltageandInternalResistanceofBattery:2008-03-12:(KZ20041000501)28361Vo.l36No.120092Tractor&FarmTransporterFeb.,2009,22.1SHEVSOC,SOC,SHEV:SHEV,,SOC,!;SOC;,SOC3,33Fig.3FuzzyLogicControlStrategy1/,SOC,/engine_on2SOCP*engine,,Preq,PmotP;,PSOC,K;,KP^maxP^,Pengine,[cs_min_pwr,cs_max_pwr][max_pwr_rise_rate,max_pwr_fall_rate],P*engine3,P*engine,,PSOC,K,,SOC,,P^max2.2MATLABSOC3{∀#,∀#,∀#},P5{∀#,∀#,∀#,∀#,∀#},K7{∀#,∀#,∀#,∀#,∀#,∀#,∀#}4~6,SOC,SOCMamdani,and14SOCFig.4MembershipFunctionofInputVariablesSOC5PFig.5MembershipFunctionofInputVariablesP6KFig.6MembershipFunctionofOutputVariablesK1Tab.1FuzzyControlRulesSOCPNLNZOPPLNNSZOPSPMPLZONMNSZOPSPMPNLNMNSZOPSP!,SOC!,K!,,SOC,,,;P!,SOC!,K!,,SOC,,,33.1ADVISOR2002,SOCADVISOR2002:M=4650kg,CD=0.5,A=4.1m2,r=0.42m,f=0.009SQR372,/38kW/6000r/min;,30kW;AC90,125kW;28,85Ah3.2UDDS,,,SOC0.5,0.70.8SOC,7,8,SOCSOC0.77SOCFig.7SOCCurveofPowerFollowingControlStrategy9UDDS,,,0.5~0.87SOC,29:8SOCFig.8SOCCurveofFuzzyControlStrategy9UDDSFig.9EngineOperatingPointsunderUDDSDrivingCycleSOC,SOC(SOC)[5],15.1L/100km,14.8L/100km,SOC,3.3UDDS,ECE_EUDC,10153,,SOC0.7,UDDS91.25km/h31.51km/h20km,17;ECE_EUDC120km/h62.44km/h10.93km,13;101569.97km/h22.68km/h4.16km,73SOC223Tab.1SmiulationResultsofThreeDrivingCyclesSOC/[L(100km)-1]SOC/[L(100km)-1]UDDS0.6798915.10.6975614.8ECE_EUDC0.6650315.90.6782715.910150.7746514.80.7007214.73.4SOC,,SOC[6]UDDS,SOC0.7,0.68~0.71,0.7SOC,SOC,,,SOC,,,3,16.5L/100km,,,,,SOC,41),,SOC2),SOC,SOC,:[1],,.[M].:,2002.[2]CERRUTOE,CONSOLIA,RACITIA.FuzzyLogicBasedEfficiencyImprovementofanUrbanElectricVehicle[C].IEEE1994,CataniaItaly:304~1309.[3]NIELSJSchouten,MUTASIMASalman,NAIMAKheir.EnergyManagementStrategiesforParallelHybridVehiclesUsingFuzzyLogic[J].ControlEngineeringPractice,2003(11):171~177.[4],.[J].,2007,34(4):32~34.[5].[D].:,2004.[6],[D].:,2001.():段建民(1959-),,,,;吴艳苹(1982-),,,;刘旭东(1975-),,,(27)5,,,:[1].[M].:,1999.[2].[M].:,1990.[3]BAKKERE,NYBORGL,PACEJKAHB.TyerModellingforUseinVehicleDynamicsStudies[J].SAE,paperNo.870421,1987.[4],.[J].,2006(26):242~244.[5]DRAKUNOVS,OZGUNERU,DIXP,eta.lABSControlUsingOptimumSearchWiaSlidingModes[J].IEEETrans.onControlSystemsTechnology,1995,3(1):79~85.[6],.ABS[J].,2007(13):1629~1631.():刘显贵(1973-),,,,30120092
