System specifications are outlined for position and velocity responses to step inputs. This leads to the design of an analog compensator to meet the desired system position performance specification. The analog compensator is tested on the actual hydraulic plant and on a 3rd order representation of the hydraulic plant. From the design of the analog compensator the system is redesigned using digital techniques and the comparable digital compensator found. This is tested on the actual hydraulic plant and on the analog model of the system. The differences between the two types of compensator are discussed. A control program for digital compensator implementation was written, and verified on the actual hydraulic plant and on the analog model of the system. 收起
