Adaptive Control System. Volume 1. Equipment and Testing
Abstract
This final report describes a two year effort to enhance the dynamic response of the load electro-hydraulic control systems used in fatigue testing by a combination of adding control functions of resonance compensation, integral control, and feedforward to the electronic controller; making frequency response measurements of the open-loop control system as a basis for closed loop adjustment; and using a small computer to assist in the optimum adjustment of the control equipments. Hardware was developed and produced for three systems including computer controlled frequency response analyzer, and manual or computer setup controller, resonance compensation and manual integral control and feedforward networks. Software was developed to make the frequency response measurements, to optimize system adjustments, to set the control hardware, and to make on-line digital data taking and data reduction possible. The individual components and the overall system was demonstrated and upgraded by application to real test setups in the Structures Test Laboratory. Significant improvements in dynamic performance and run time were achieved. Adaptive setup and on-line adjustment are now possible.
