Engine control systems require software tasks that are activated at predetermined angular values of the crankshaft, thus generating a computational workload that varies with the engine speed. To avoid overloads at high rotation speeds, such tasks are implemented to self adapt and reduce their computational demand by switching mode at given rotation speeds. For this reason, they are referred to as adaptive variable rate (AVR) tasks. Analyzing the schedulability of AVR tasks is an interesting cyber-physical problem that requires proper models and assumptions.
This talk explains the problem of scheduling and analizing the timing behavior of control applications including AVR tasks, illustrating existing solutions and stating possible open problems.
