Abstract
Apparatus and a method for monitoring the performance of control algorithms, providing a safeing subsystem for a vehicle, particularly an agricultural windrower, for determining when a controlled system such as the propulsion system is no longer tracking a reference input signal sufficiently well. An appropriate action can then be executed, such as outputting a fault signal and/or shutting down the controlled system. An exponentially decaying integrator can be used to monitor the tracking errors.
