Compensation for generic servoamplifier usage with high performance direct drive valves

摘要

A compensation design allows for use of a generic servoamplifier for multiple types of actuator Direct Drive Valves (DDV). Cost savings can be realized by using common electronics applied to multiple actuator types. The implementation allows for design of the compensation directly from experimentally or analytically derived frequency performance curves of the generic servoamplifier resulting in the performance comparable to a custom servoamplifier for the direct drive valves.
