Abstract
In an electro-pneumatic system for controlling a double-acting pneumatic actuator having first and second working chambers, first and second preliminary pneumatic control components generate first and second preliminary pneumatic control signals transferred to respective first and second main pneumatic control components having outputs connected to the respective first and second working chambers. An electronic splitter circuit precedes the first and second preliminary pneumatic control components for splitting and inverting an electrical control signal input to the splitter circuit around an electrical mean control value to create first and second mirror-inverted electrical control signals respectively connected to the respective first and second preliminary pneumatic control components. The electrical mean control value is adjustable such that the first and second preliminary control components respectively generate the respective first and second preliminary pneumatic control signals mutually inverted around a pneumatic mean value.
