For realization of the online real time simulator, a motor mathematical model based on the three phase stationary coordinate is solved using a fourth order Runge-Kutta algorithm in real time. The Runge-Kutta algorithm is required since the model includes non-linear operation, such as, trigonometric functions, square waves generated by a PWM inverter and limiter circuits, so on. The experimental system based on the RTLinux accomplishes both the motor control and the real time simulation at the same time in 200 µs control period. The online simulation results show considerable coincidence with the experimental results.

The estimation of speed and rotor angle is based on extended programmable cascaded low pass filter (EPCLPF) which reduces the dc-offset effect at low speed area effectively. Thus the sensorless control at very low speed area is possible. At

The controller consists of a digital modified-IPD controller for speed loop and a digital PI controller for current minor loop. The six controller gains are determined by Differential Evolution algorithm. The Differential Evolution is one of optimization techniques and a kind of evolutionary computation technique. In this paper, we have applied the DE/rand/1/bin strategy to design swift the optimal controller parameters. Furthermore, we consider the parameter identification method of 2-inertia experiment system by the Differential Evolution. Finally, the effectiveness of the proposal methods has been confirmed by the computer simulations and the experiments.

In this paper to control motor at low speed region a modified programmable cascaded low pass filters (MPCPLF) is proposed. MPCLPF is suggested because programmable cascade low pass filters (PCLPF), which has previously been applied to induction motors, has some problems in low speed area. In addition PCLPF is affected by the parameter fluctuation. To overcome the problem an online parameter identification method based on block pulse function also is proposed. In this method the parameter identification is not affected by position estimation accuracy. The experimental system includes a PC-based control with real time Linux as operating system. And to acquire data form sensors and to send commands to the system an ALTERA complex programmable logic device (CPLD...

The estimation of speed and rotor angle is based on extended programmable cascaded low pass filter (EPCLPF) which reduces the dc-offset effect at low speed area effectively. Thus the sensorless control at very low speed area is possible. At startup condition, the rotor angle is assumed rotating at synchronous speed, and because the estimation rotor angle is valid at very low speed, its error decreases rapidly after the initial rotor movement. Thus motor start up without torque jerk is achieved. The experimental results, which are done by a RT-Linux pc based system, show the estimated and the actual rotor angle at very low speed region are agreed and sensorless vector control is achieved at very low speed area as well as high speed. Also the motor startup at standstill condition is possible.

Although rotor angle calculation using flux estimation is a simple approach, the dc offset can cause an increasing error in pure integrator used in this estimator. In this paper to control motor at low speed region a modified programmable cascaded low pass filter (PCPLF) is proposed. The use of PCLPF has previously been applied to induction motors. However it can make some problems especially at low speeds. Hence in this paper to avoid of the PCLPF drawbacks a novel method is suggested. The experimental system includes a PC-based control with real time Linux as operating system. And to acquire data form sensors and to send commands to the system an ALTERA Complex Programmable Logic Device (CPLD) is used. The experimental results show the proposed method performs well and speed and angle estimation is correct also sensorless vector control is achieved at low speed as well as high speed using the proposed method.
