Summary on Grant Application Form |

This proposal is concerned with the application of model reference adaptive control schemes for the control of electro-hydraulic load-sensing systems. It is proposed that the research is undertaken jointly by teams from the Universities of Bristol and Bath. The aim will be to achieve consistent transient performance, regardless of operating conditions of the circuits, whilst achieving high energy efficiency. This presents a significant challenge: such multi-variable systems exhibit variable-order transfer functions with time-varying coefficients. However, the breadth of experience on hydraulic systems and their control at Bath, synergistically coupled with the novel research on adaptive systems at Bristol, suggests that the proposed programme will have a high likelihood of success. The programme involves the formulation of real-time adaptive control algorithms applicable to a wide range of load-sensing circuits. This will be undertaken through computer simulation and experimentation. It will involve comparative simulation studies on generic load sensing problems, using Minimal Control Synthesis (MCS) with conventional controller benchmarks. These studies will be supported by the necessary theoretical developments of MCS into the robustness and stability issues associated with variable order structural changes within the plant. The computer simulation will be supported and verified by an experimental programme; the test rig employed will contain the principal elements of a loading-sensing system.
