Measuring Unstable Plant Responses Without Breaking the Control Loop

 Discover an easy-to-use method for measuring plant transfer functions without breaking the control loop. This technique is based on computing two cross-spectrums—thus the name double cross-spectrum measurement. It works on both unstable and stable plant responses. As long as the overall closed-loop response is stable, this measurement provides robust plant transfer function estimates.
