Figure 1-1:  Example  of undesired shift event  depicted  in  the pressure  domain achieved by  purposely  altering  the  open-loop  pressure  command  of the  ONC  clutch  as  well  as torque  and  speed  ratio  changes.
Figure  2-3:  Block  diagram  of the  overall  clutch  model.  The  region  is  determined  by the  clutch  piston  position  x
Figure  2-4:  Regions  of the  shift  roughly  indicated  without  knowing  the clutch  piston position
Figure  2-5:  Input/output  response  and  model  for  Regions  1 and  2.

The speed variation in the open-loop control is suppressed by the closed-loop control of the speed, and the speed waveform of the system during the whole blanking process is

We use a hydrodynamic model (cf., Sections 3.1 and 3.2) to investigate the consistency of river bed undulations derived from stage-discharge rating curves and the spatial and

In real-time classical approach to FTC problem, a suitable controller is selected from the set through the monitoring of plant with a certain logic that takes the role of an

We design a novel hybrid controller, which ensures zero steady-state error and a fast non-overshooting response.. We show that the controller parameters can be conve- niently
