- W2186047730 abstract "Thispaperpresents practical aspects andresults obtained withacontroller structure basedontwophasecurrent control. Adaptive controllers wereusedtoimprove thecontrol quality. At theend,controller structures formagnetic flux weakening modeareproposed. Thereisacontinuous growth ofsynchronous motors usage, mostly withpermanent magnets inthefield ofelectric drives. Themotors areusedmainly asservo drives, butaremoreand moreusedalsoastraction drives. Otherapplications for synchronous motorsarespecial andauxiliary motors, where theyreplace commutator motors. Atthedivision ofelectrical engineering ofthefaculty ofmechanical engineering atthe CzechTechnical University inPrague, wefocus ourattention onsynchronous motorusage inthefield oftransportation. This research isdoneinthescope ofJosef Bozek's research center ofengine andautomotive engineering. We areinterested in traction motors,special andauxiliary motorsforthe automotive industry wereDC motors ornonelectric motors are being used. Insomecasesthere isa needforhighspeed motors. Besides somespecificity ofautomotive engineering there isalso ahighpressure onlowcostcomponents aslarge quantities areproduced andduetohigh pressure onthemarket. Therefore oneofourgoals isalso thelowcostoftheproposed solution. Themethods forsynchronous motortorque control canbe divided intotwomaingroups: control ofphasecurrent immediate values basedonrotor position andcontrol inthe transformed coordinate system. The mostusedmethodbasedon coordinate system transformation islinear vector control ind,qaxes, coupled to rotor position. Thismethodisananalogy toasynchronous motorvector torque control. Thismethod gives goodcontroller results also forthereason that itisusedtocontrol steady state variables instead ofinstantaneous phase current values. Itis usedmainly fordrives withhigher dynamics demands, middle andhigher powerdrives including traction drives. Thanks to thecomputing poweroftoday's processors andbuild-in HW peripherals, its implementation isnotdifficult. Methods basedonphase current control withfeedback to rotor's instantaneous position wereusedpreviously when today's microcontroller techniques werenotavailable. Thesemethods wereimplemented inanalog orhybrid controllers. Theadvantage ofthesemethodsarelower computation demands asinisnotnecessary tocalculate the coordinate systemtransformations asitisthecasefor coordinate system control techniques. Thedisadvantage isthe needtocalculate timevariable phase current values - control variables. Thisleads toproblems inachieving higher quality control, mainlyforhigher speeds. Thisbecomesmore significant aswe aredecreasing theratio between PWM frequency andthefrequency ofthefirst current harmonics. Phasecurrent controllers canbeusedwiththeinverter havinga voltage inputas linear controllers or on-off controllers. On-off controllers canbefound inservodrives or inlowpowerbrushless motors. Inourworkwefocused onimproving phase current control properties. On-off controllers weretested (1)butduetothe necessary increase incontroller computation frequency and inverters switching frequency andduetopotential EMC problems forthis controller solution we focused mainly on linear control.
