EPS System with PMSM Motor and Toshiba TPHR7904PB Power MOSFET JSAE 2025 Designer241497 × Member for 3 years 10 months 170 designs 6 groups I'm a member of the PartQuest Explore Promoto. https://explore.partquest.com/node/694833 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/694833"></iframe> Title Description <p>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.</p> <p>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.</p> <p>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.</p> About text formats Tags PMSMPWMSVMD-QEPSPower SteeringTPHR7904PB Select a tag from the list or create your own.Drag to re-order taxonomy terms.

EPS System with 1D PMSM Model and DQ/SVM Drive JSAE 2025 Designer241497 × Member for 3 years 10 months 170 designs 6 groups I'm a member of the PartQuest Explore Promoto. https://explore.partquest.com/node/694831 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/694831"></iframe> Title Description <p>This Electric Power Steering (EPS) System design includes a MotorSolve generated Permanent Magnet Synchronous Machine (PMSM) model and a PWM Drive circuit. 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.</p> <p>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, a non-linear gain profile is specified in the "torque_assist_table" function, and a lead-lag compensator is used to improve system stability.</p> <p>In a companion version of this design, "EPS System with MotorSolve Generated PMSM Model and Ideal Drive", Clarke and Park Transform models are used with a continuous ideal voltage drive. This shows the ability to develop motor controls and drives at the abstract level and also at the circuit level.</p> About text formats Tags PMSMPWMSVMD-QMotorSolveEPSPower Steering Select a tag from the list or create your own.Drag to re-order taxonomy terms.
