To verify the feasibility in practical implementations, the offered control method integrated to the full-order observer with proposed feedback gains is experimented in this section. The installation and block diagram of the experimental system are shown in Fig. 9, Fig. 10. The parameters of a three-phase induction motor are listed in Table 1. A DC generator with 1 kW, 220 V, 5.2 A and 2000 rpm connected to a resistor is simulated as mechanical load. All algorithms for control and stator flux estimation are processed on DSP number ADMC331 with the sampling time 100 μsec to ensure that it will be enough for processing and data acquisition time and conversion time of ADC and DAC. The speed commands are stepped from standstill to 1400 rpm and standstill to 120 rpm for positive high and low speed ranges, respectively, and likewise, they are stepped from standstill to −1400 rpm and standstill to −120 rpm for negative high and low speed ranges, respectively. When the speed response reaches the steady-state condition, the full load torque is taken in each testing situation. The speed and torque responses in positive and negative high speed ranges are depicted in Fig. 11, Fig. 12, respectively. Speed and torque responses in positive and negative low speed ranges are shown in Fig. 15, Fig. 16, respectively. The speed responses of all testing situations can reach the speed command accurately in steady-state conditions. The settling time of speed response in high speed range is approximately 0.7 s as shown in Fig. 11, Fig. 12, and in low speed range is approximately 0.1 s as shown in Fig. 15, Fig. 16. After speed response of each testing situation reaches steady-state condition, mechanical load is connected to motor, the speed response drops a little then returns to the speed command in short time similarly, the speed response increases a little then also returns to the speed command again in short time as well when the mechanical load is released, which can be seen from speed response in Fig. 11, Fig. 12, Fig. 15, Fig. 16. The torque responses can respond to the load torque precisely and quickly as seen from Fig. 11, Fig. 12 for high speed range and Fig. 15, Fig. 16 for low speed range. Fig. 13, Fig. 17 represent the estimated stator fluxes under full load condition in high and low speed ranges, respectively. From figures, it is found that the estimated stator fluxes do not suffer from saturation and drift problems both in high and low speed ranges. The magnitudes of the estimated stator flux in d-axis and q-axis are equal, both in high and low speed ranges. The estimated stator flux in d-axis is apart from q-axis 90° for high speed range and the result is still the same for low speed range. The trajectory of the estimated stator fluxes in Fig. 13, Fig. 17 are presented in Fig. 14, Fig. 18, respectively. They own the circular shape with the similar radius that means the stator fluxes are accurately estimated and smoothly controlled. These experimental results clearly verify the feasibility in practical implementations. The offered control method has fast dynamic responses and can control speed, torque and magnitude of stator flux precisely, both in high and low speed ranges. The full-order observer with proposed feedback gains can estimate stator flux accurately. Furthermore, the offered control method combined with the full-order observer with proposed feedback gains has stability in all the ranges of operations.
