Motor control

UET-designed motor driver chip made its way to IEEE

The Department of Electrical Engineering at Lahore University of Engineering and Technology (UET) is on track to make the institute proud by publicizing their innovative chip designs globally.

A team from UET Lahore Department of Electrical Engineering including Dr. Tayyab Mehmood, Dr. Muhammad Tahir, Dr. Ubaid Ullah Fayyaz and Mr. Umer Shahid designed a “Servo Motor (Sermo) on a Chip (SoC)” controller system which is capable of providing four programmable Proportional Integral Derivative (PID) control units with Quadrature Encoder (QEI) inputs and Pulse Width Modulation (PWM) outputs.

The design was submitted to the IEEE Solid-State Circuits Society (SSCS) open source “PICO” design competition. The SSCS aims to help build and connect to new communities for IC innovation and its democratization towards a new wave of global impact. Collectively, 18 designs were selected from 15 different countries, of which Sermo-SoC was granted a shuttle seat out of the four dedicated seats and the design was fabricated with sponsorship from the IEEE SSCS. The Sermo-SoC is a motor control subsystem that serves as a research vehicle for exploring the design space of new motor control algorithms. It turns the Efabless Caravel SoC into a powerful servo controller.

Additionally, Sermo-SoC was featured in the IEEE Solid-State Circuits Society Fall 2021 Issue flagship magazine on the PICO program. The Platform for Integrated Circuit Design Awareness (PICO) program is focused on supporting the rise of the open source ecosystem through sponsored IC manufacturing cycles. The open source design is showcased in the department’s GitHub code bank
