Pneumatic actuators are often used in industrial automation for reasons related to their good power/weight ratio, easy maintenance and assembly operations, clean operating conditions and low cost. This set of advantages, is, however, made up for by the difficulties met during the design.

The authors propose a new mathematical tool to investigate the influence of cable characteristics upon pulse voltage transients and their associated differential mode (DM) currents in PWM long cable drives. Even if reflected wave transient voltages have received considerable investigation for...
