A position control system is used for controlling a fluid operated cylinder having at least one fluid chamber defined by a piston located within a housing for movement between first and second end limits of travel. The system includes at least two electrically actuated proportional flow control valves connected to each port of the cylinder for selectively and proportionally controlling fluid flow into and out of the at least one chamber. At least one pressure sensor is provided for measuring fluid pressure with respect to each chamber. At least one discreet position sensor is located adjacent a midpoint of the cylinder for sensing a discreet centered position of the piston. A controller includes a program and is operably connected for controlling actuation of the at least two valves in response to pressure measured by the at least one pressure sensor and location measured by the at least one position sensor.

An amusement park attraction includes an attraction feature. The attraction feature includes a fluid actuator having an inflatable mass, the inflatable mass being fluidly connected to a source of pressurized fluid to enable inflation of the inflatable mass. Fluid control devices are configured to adjust inflation of the inflatable mass, and sensors are configured to monitor state properties of the fluid actuator. A controller is communicatively coupled to the fluid control devices and the sensors. The controller is configured to controllably inflate the inflatable mass based at least on feedback from the sensors to cause the fluid actuator to impact an object. The controller is configured to control the inflation of the inflatable mass to adjust parameters of the fluid actuator to maintain a force exerted by the fluid actuator on the object to within a predetermined range.

A method for processing operating data (e.g., position, setpoint, and pressure) for a valve assembly. The method is configured to associate characteristics of operation for the valve assembly with a root cause and / or a contributing factor. In one embodiment, the method can assign a first amplitude with a value that quantifies movement or “jump” of the valve stem that results from stick-slip on the valve assembly. The method can also assign a second amplitude with a value that quantifies a change in the data for the setpoint. The method can further ascertain the relationship or “position” of the first amplitude relative to the second amplitude, or vice versa. The method can use the relationship between the first amplitude and the second amplitude to indicate the root cause of the operation of the valve assembly.
