Description

Permanent Magnet Synchronous Machine (PMSM) and PWM Drive circuit, with mechanical load. The drive includes a D-Q control algorithm, and uses space-vector modulation (SVM) to generate the digital PWM signals to the switches of the bridge.The waveform plot in the upper left shows the drive command (light blue waveform), with values 0 to 1, where 1 is commanding the maximum quadrature current of 10 A. The motor's response is the output shaft angle in radians (orange waveform), and shows that increasing torque command results in greater rotational displacement against the load spring. The waveform plot in the upper right shows the actual motor torque (green waveform) and the A-phase current (dark blue waveform).In a companion version of this design, "PMSM Motor And Ideal Drive", Clarke and Park Transform models are used with a continuous ideal voltage drive.This shows the ability to develop motor control and drives at the abstract level and at the circuit level.In yet another version of this design example, the ideal switches will be replaced with actual power MOSFET device models. This can help in bridge component sizing and performance specification.

Description

Permanent Magnet Synchronous Machine (PMSM) and PWM Drive circuit, with mechanical load. The drive includes a D-Q control algorithm, and uses space-vector modulation (SVM) to generate the digital PWM signals to drive the Power MOSFET switches of the inverter.There are two other versions of this design. The first, "PMSM Motor And Ideal Drive", uses continuous Clarke and Park Transform models and an ideal voltage drive to represent the main features of the field-oriented control system., Another version, "PMSM Motor and PWM Drive", it similar to this version but uses ideal switches.This version is the most detailed and therefore simulated the most slowly. It is well suited for understanding the performance of the Power MOSFETs in the context of the system, In the waveform plot on the right, the actual motor shaft angle (orange waveform) and the A-phase current (dark blue waveform) are shown. These are very similar to the results for the other two versions of the design. But the waveform plot on the left provides insight into the performance of the C-phase inverter pull-up switch. The MOSFET current Ids (green waveform), and the average power dissipated in the device (red waveform) are shown. This design can be used to size specific parts in the drive electronics, by comparing the operating conditions to which they are exposed, relative to their rated operational limits.

Description

This Electric Power Steering (EPS) System design includes a PWM Switching Inverter circuit that uses Toshiba TPHR7904PB Power MOSFETs. The drive includes a D-Q control algorithm, and uses space-vector modulation (SVM) to generate digital PWM signals. These control the ON/OFF state of the switches.The mechanical load model includes static and kinetic friction, a steering force that varies with rack displacement, as well as various mass, inertia, damping and spring/stiffness elements of the steering system. The steering torque, applied by the vehicle's driver, is assisted by torque from the motor scaled by the gear ratio. For the control, the first gain/pole-zero block (far left) specifies the amount of "torque_assist" gain (assist torque as a multiple of the vehicle operator's torque applied to the steering wheel), as well as providing compensation to improve system stability.This design focuses on the performance of the switches in the inverter circuit, including tracking of the thermal characteristics of one representative switch. In a companion version of this design, "EPS System with PMSM - Pre-Circuit Design for Toshiba Drive", Clarke and Park Transform models are used with a continuous ideal voltage drive, and provides much faster simulation results with a focus on overall system dynamic performance.
