Abstract: A method includes receiving a first input indicating at least a selected controller type and generating, based on the first input, a model that represents a controller corresponding to the selected controller type. The method also includes receiving a second input indicating at least one functional aspect of the selected controller type, updating, based on the second input, the model to represent the at least one functional aspect of the selected controller type, and compiling, using the model, a binary file that represents, at least, the at least one functional aspect of the selected controller type. The method also includes uploading the binary file to a controller corresponding to the selected controller type.

Abstract: Technical solutions described herein include a method of controlling, in an electric power steering system, a steering angle according to a target steering angle by computing an initial value of an integral control term in a proportional integral derivative (PID) control loop used to calculate a control output signal, such as a motor torque command. The initial value of the integral control term is computed as a negative of the initial value of the feedforward term minus the initial value of the feedback term. The initial value of the integral control term corresponds to an initial value of a control output. Accordingly, the technical solutions described herein facilitate handling non-zero initial condition in Electric Power Steering angle control.

Abstract: According to the technical solutions described herein, an example method for frequency tracking based friction detection includes receiving, by a filter module, an accelerometer signal from an accelerometer coupled with an assist torque system. The method further includes estimating, by the filter module, harmonic content in the accelerometer signal based on an order frequency of the assist torque system. The method further includes in response to the harmonic content that is detected being greater than or equal to a predetermined threshold, initiating a friction estimation in the assist torque system. The method further includes adjusting an amount of torque being generated by the assist torque system based on an estimated friction in the assist torque system.
