ABSTRACTNowadays the Induction Motor 1M drive due to its high perfoffi1ance high reliability andlow cost has been extensively used in different industries However due to complicateddynamic model of this motor also due to non measurablestate variables the control of thismotor is not so easy In the last three decadesthe vector control method has been proposedfor independent control of 1M torque and flux Although this method is powerful it is notcapable of controlling the torque and flux independently in the transient state as well as tocontrol the motor efficiency in the steady state To solve these problems and also in orderto eliminate the current regulators used in the vector control of the 1M the Direct TorqueControl DTC of the 1M has been proposed This method compared to vector controlmethod is only sensitive to the stator resistance and in addition easy to implement It isworthwhile mentioning that the 1M speed control is also done using a feed forwardcontroller Sensorless speed control increases the 1M system dive reliability as well asreduces the noise effects However rotor resistancevariations with motor temperature andskin effects make the speed sensorlessdrive operation complicated and even impossible To come up the above drawbacks a new adaptive nonlinear flux observer is proposedwhich provides the simultaneous estimation of the 1M speed stator flux and stator androtor resistances In this thesis using a PI predictive controller of stator flux angle a newDTC Space Vector Modulation DTC SVM technique is first described for the speedsensorlesscontrol of 1M drive Then a Sliding Mode SM rotor flux observer is introducedthat estimate the rotor speed ad rotor resistance simultaneously Moreover in this thesis aDTC SVM scheme is described which is on the basis of input output linearizing with thetorque and stator flux as the output variables In this method using the stator currents andvoltages measurement a novel adaptive Lyapunov based flux observer is designed in orderto estimate the rotor speed rotor and stator resistancessimultaneously If the PersistencyofExcitation condition is satisfied the exponential convergence of the actual stator flux andmotor torque to their reference values is proved Furthermore to investigate the systemcontrol and adaptive flux observer performances a PC based real time system is designedand implemented using the DAQ cards voltage and currcnt transducers To fecd a threephase 1M a 5 kw two level three phase SVM inverter using a CPLD device is designedand implemented Finally the simulation and experimental results are obtained These twosets of results are in close agreement and in addition confirm a good performance forclosed loop control of an 1M systemdrive e J I Ilf f V it
