    摘要: A valve control system (10) for achieving proportional response using inexpensive on-off valves (16) commonly used in machine and robotic applications and other pneumatic/hydraulic systems. A proportional response is achieved from each on-off valve (16) by interposing a single continuously proportional inlet valve (18) actuated by linear or non-linear signals to regulate the transfer of a media, whether air or fluid, to the actuated on-off valve (16) via a common galley (22). The actuation signals are preferably provided by a microcontroller (14) that can be programmed with more than one algorithm for generating different types of actuation signals. Furthermore, a non-linear mechanical response can be linearized by generating a non-linear actuation signal to produce a non-linear media transfer which when combined with the non-linear mechanical response results in an overall linear response.
