How AI Compensates for PID Controller Limitations in Electric Vehicles with STMicroelectronics

How can artificial intelligence transform electric vehicle performance? Discover the groundbreaking application of neural networks to motor control challenges that even Formula 1 legend Michael Schumacher helped identify.The automotive industry's electrification demands increasingly sophisticated silicon solutions, particularly for traction inverters controlling electric motors. Traditional control systems face a fundamental challenge: they must operate at extraordinary speeds (currently 20kHz, trending toward 100kHz) while managing rapid transitions between states. When drivers make sudden accelerator changes, conventional PID controllers produce energy-wasting overshoots that drain precious battery power.Our research presents a novel approach using neural networks to compensate for these limitations. By generating time-varying correction factors, our AI solution reduces maximum overshoots by up to 70% in demanding scenarios. This innovation represents a critical advancement for electric vehicle efficiency, potentially extending range and improving performance.What makes this application particularly fascinating is the extreme time constraints. While most AI applications process data at relatively leisurely rates (think 30 frames per second for vision systems), motor controllers must complete their calculations within microseconds. Our current implementation achieves 70-microsecond inference times on automotive-grade microcontrollers, with further optimizations planned through hardware acceleration.The collaboration between academic researchers and industry partners (MathWorks and STMicroelectronics) demonstrates the power of combining simulation expertise with real-world deployment capabilities. Using Simulink as the development platform and ST's developer cloud for automatic deployment to physical microcontrollers, we've created a streamlined methodology for applying AI to automotive control systems.Want to dive deeper into the technical details?
