Predictive Control Applied to Transient Engine Testbeds 880487

Transient control of speed and torque on the testbed is becoming increasingly important for modern engine development. This paper describes the application of a modern control technique, Generalised Predictive Control (GPC) to this problem. By using system identification, coupled with the GPC design algorithm, the controller is automatically tuned by a computer. The best performance can then be obtained for each installation. The results presented show that, on a testbed with a standard eddy current dynamometer, tight control of transient speed and torque can be achieved using these techniques. This enables transient testing facilities to be made much more widely available.
