INTEGRATED CONTROL AND DIAGNOSTICS SYSTEMS
First Claim
1. An integrated control and diagnostic system comprising:
- a diagnostic module to generate a diagnostic signal indicative of the heath of a controlled system; and
a control module integrated into the controlled system with the diagnostic module, wherein the control module generates a driving output for the controlled system based on a control optimization algorithm and the diagnostic signal.

Abstract
An integrated control and diagnostics system for a controlled system (e.g., a motor) includes a diagnostics module and a controller coupled to the motor. To optimize operation, the diagnostics information signal is used to modify the control provided by the controller as required. Moreover, the output of the control module is coupled to the diagnostics module so that the health assessment made by the diagnostics module can be based at least in part on the output of the controller. The invention uses a model-based diagnostics approach that allows integration of control algorithms with diagnostics algorithms to intelligently trade off optimizing performance to avert or accommodate failures, and to meet performance requirements in a wide range of applications.

12. A control and diagnostic system comprising:
-
a diagnostic module to produce a health assessment signal indicative of the health of a controlled system; and
a processor to receive the health assessment signal from the diagnostic module, process the health assessment signal, and transmit the processed signal to a control module coupled to the diagnostic module and integrated into the controlled system, wherein the control module generates a driving output based at least in part on the processed signal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
