Abstract :
The wide applications of cyber-physical systems (CPS) call for effective design strategies that optimize the performance of both computing units and physical plants.We study the task scheduling problem for a class of CPS whose behaviors are regulated by feedback control laws. We co-design the control law and the task scheduling algorithm for predictable performance and power consumption for both the computing and the physical systems. We use a typical example, multiple inverted pendulums controlled by one processor, to illustrate our method.
