The speed of the input rotor can be controlled using feedback control of the engine speed and feedforward control of the ICE torque.
Since the compensation control for the spool valve dead zone is a feedforward control, it is affected by the current-flow rate characteristics of the linear solenoid valves, variation in the length of the spool valve dead zone, and the like.
1 depicts the general scheme for feedforward control along with feedback trim, but can be called a hybrid structure since it can be used as a control scheme for plant structures with and without [P.
Wiener models are also used, for example as a robust nonlinear internal model control of stable Wiener systems [20], or block-oriented feedforward control with demonstration to Wiener modelling [25], or modelling of memristor-based chaotic systems using nonlinear Wiener adaptive filters [24].
Feedforward control shows a significant effect by predicting in advance against the vibration of the base platform and direct disturbance of the machine.
A current trend in human-centered robotics is to rely more on feedforward control and less in feedback effort to achieve higher system efficiency and some level of safety upon collisions with the environment.
Another network motif that can underpin adaptation and threshold response is incoherent feedforward control (Ma et al.
