Description

This design includes an ideal Permanent Magnet Synchronous Machine (PMSM) model, as well as a continuous D-Q controller and drive circuit. 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 compensator is used to improve system stability.

Note that this is a "tunable" design. Many of these system parameters can be changed by the user. Then a new simulation can be run and the updated results can be observed in the waveform viewers.

In a companion versions of this design, "EPS System with MotorSolve Generated PMSM Model and Ideal Drive", the ideal PMSM is replaced with a more realistic motor model generated by MotorSolve, the motor design tool. That model includes cogging torque, saturation and torque ripple behavior, which is seen to have a significant effect in this power steering application.

A second companion design, "EPS System with MotorSolve Generated PMSM Model and DQ/SVM Drive", uses both the MotorSolve motor model and also a sampled-data D-Q control algorithm and space-vector modulation (SVM) to control the switches in a power electronics circuit. This shows the ability to develop motor control and drives at the abstract level and also at the circuit level.

Description

Este diseño incluye un modelo ideal de máquina síncrona de imanes permanentes (PMSM), así como un controlador DQ continuo y un circuito de accionamiento. El modelo de carga mecánica incluye fricción estática y cinética, una fuerza de dirección que varía con el desplazamiento de la cremallera, así como varios elementos de masa, inercia, amortiguación y resorte/rigidez del sistema de dirección. El par de dirección, aplicado por el conductor del vehículo, es asistido por el par del motor escalado por la relación de transmisión. Para el control, se especifica un perfil de ganancia no lineal en la función "torque_assist_table" y se utiliza un compensador de adelanto para mejorar la estabilidad del sistema.

Tenga en cuenta que este es un diseño "ajustable". El usuario puede cambiar muchos de estos parámetros del sistema. Luego, se puede ejecutar una nueva simulación y se pueden observar los resultados actualizados en los visores de formas de onda.

En una versión complementaria de este diseño, "Sistema EPS con modelo de PMSM generado por MotorSolve y transmisión ideal", el PMSM ideal se reemplaza por un modelo de motor más realista generado por MotorSolve, la herramienta de diseño de motores. Ese modelo incluye par de torsión, saturación y comportamiento de ondulación de par, que se observa que tiene un efecto significativo en esta aplicación de dirección asistida.

Un segundo diseño complementario, "Sistema EPS con modelo PMSM generado por MotorSolve y variador DQ/SVM", utiliza tanto el modelo de motor MotorSolve como también un algoritmo de control DQ de datos muestreados y modulación de vector espacial (SVM) para controlar los interruptores en un circuito de electrónica de potencia. Esto demuestra la capacidad de desarrollar el control y los variadores de motor a nivel abstracto y también a nivel de circuito.
