E-Motor Position Control Strategies

In automotive e-motor control, complex electro-mechanical systems can cause difficulty in determining all relevant parameters in advance. So, it could be necessary to make trade-offs to provide a cost-effective solution yet covering the desired specifications. In these cases, statistical or heuristic approaches can be used to verify the quality of the solution.

Characterize the behavior of an electro-mechanical system and design a specific motor control model and related software to balance performance limitations imposed by the component cost-reduction for high scale production. The required performance of the actuator operation had to be guaranteed also for high temperature and over voltage conditions.

EMA Global worked with Customer’s development and production Teams to study the characteristics and non-linearity of the electro-mechanical system with the help of a Matlab/Simulink model. A specific testbench has been configured to automate collection of data, validate, tuning and validate the control strategy in order to achieve the requested performances in any condition.
