Patent ID: 8301307

Claim:
A pneumatic actuator system ( 200 ) comprising a pneumatic actuator ( 100 ) including an actuator cylinder ( 102 ) and an actuator component ( 108 ), with the pneumatic actuator system ( 200 ) being characterized by: a first conduit ( 207 ) and a second conduit ( 208 ) coupled to the pneumatic actuator ( 100 ); one or more feedback sensors configured to provide one or more actuation feedback values, with the one or more actuation feedback values including a calculated actuation force value generated from a first pressure signal and a second pressure signal; an actuator valve ( 213 ) coupled to and providing a first pneumatic pressure to the first conduit ( 207 ) in a first actuation phase and providing a second pneumatic pressure to the second conduit ( 208 ) in a second actuation phase, wherein the second actuation phase is independent of the first actuation phase; and a controller ( 240 ) coupled to the one or more feedback sensors and the actuator valve ( 213 ), with the controller ( 240 ) configured to receive the one or more actuation feedback values from the one or more feedback sensors and control the actuator valve ( 213 ) in order to actuate the actuator component ( 108 ) according to an actuation profile, according to the one or more actuation feedback values including the calculated actuation force value, and according to the first actuation phase, the second actuation phase, or a combined first and second actuation phase.
