This paper proposes a modified predictive direct torque control (PDTC) application-specific integrated circuit (ASIC) of a motor drive with a fuzzy controller for eliminating sampling and calculating delay times in hysteresis controllers. These delay times degrade the control quality and increase both torque and flux ripples in a motor drive. The proposed fuzzy PDTC ASIC calculates the stator's magnetic flux and torque by detecting the three-phase current, three-phase voltage, and rotor speed, and eliminates the ripples in the torque and flux by using a fuzzy controller and predictive scheme. The Verilog hardware description language was used to implement the hardware architecture, and the ASIC was fabricated by the Taiwan Semiconductor Manufacturing Company through a 0.18-µm 1P6M CMOS process that involved a cell-based design method. The measurements revealed that the proposed fuzzy PDTC ASIC of the three-phase induction motor yielded a test coverage of 96.03%, fault coverage of 95.06%, chip area of 1.81 × 1.81 mm 2 , and power consumption of 296 mW, at an operating frequency of 50 MHz and a supply voltage of 1.8 V.

In modern motor speed control system, as PI regulator is in the speed loop of vector control and direct torque control, the motor system does not have a good performance in dynamic response. This paper presents a new control method which can improve dynamic response of a motor. The method can accurately calculate the needed forward vector, zero vector and switch time during the dynamic process by utilizing principle of torque impulse balance control and the optimal combination of vector idea thus can realize quick dynamic speed response without overshoot in theory. This control method can be used to control and optimize the dynamic process of various motor and is of great significance for motor control, servo, etc.

This study developed a predictive direct torque control (PDTC) application-specific integrated circuit (ASIC) with a fuzzy proportional-integral-derivative (PID) controller and a new round-off calculation circuit for improving the ripple response of a hysteresis controller when sampling and calculating delay times in an induction motor drive. The proposed PDTC ASIC not only calculates the stator's magnetic flux and torque by detecting three-phase currents, three-phase voltages, and rotor speed but also eliminates large ripples in the torque and flux by using the fuzzy PID controller. Furthermore, the proposed round-off algorithm reduces the calculation error of the composite flux. A fuzzy voltage vector switching table is proposed not only to speed up the calculating speed but also to resolve the instability generated by its large torque and flux ripples. The Verilog hardware description language was used to implement the hardware architecture, and the aforementioned ASIC was fabricated using the 0.18-μm 1P6M CMOS process of the TSMC by employing the cell-based design method. The predictive calculations, fuzzy PID controller, fuzzy voltage vector switching table, and round-off calculation algorithm improved not only the ripple issue faced in traditional direct torque control but also the control stability and robustness. The measurement results indicate that the proposed PDTC ASIC has an operating frequency, a sampling rate, and a dead time of 50 MHz, 100 kS/s, and 100 ns, respectively, at a supply voltage of 1.8 V. The power consumption and chip area of this ASIC are 1.0027 mW and 1.169 × 1.168 mm 2 , respectively. The main advantages of the proposed PDTC ASIC are its low power consumption, small chip area, robustness, and convenience.INDEX TERMS Direct torque control (DTC), Predictive calculation, fuzzy PID controller, round-off algorithm, application-specific integrated circuit (ASIC), induction motor (IM), hardware description language (HDL).
