Latest Patents
One of Hanlong Yang's latest patents is focused on misfire detection in an internal combustion engine. This method and system for misfire detection acquires a series of acceleration data representative of the engine's acceleration behavior. The data is sampled to obtain acceleration data samples at a rate sufficient to capture up to fourth-order perturbations. The samples are then filtered to provide bandwidth-limited samples, which are processed through at least two channels. The first channel enhances harmonic phenomena through pattern matching, while the second channel enhances random phenomena through pattern cancellation. This innovative approach allows for the detection of hard and random misfires based on the magnitude of the filtered acceleration data samples. Additionally, a third channel can be added to detect multiple misfires.
Another significant patent by Yang involves tracking control for electronic throttle systems. This electronic throttle controller incorporates a feedforward control, a PID controller, and a sliding mode control. The PID controller generates a feedback term that compensates for an error signal, while the sliding mode control generates a second feedback term that incorporates a solution to a Lyapunov equation applied to the error signal. The adder combines these feedback terms with the feedforward control to generate a control signal, enhancing the performance of electronic throttle systems.
