In general, various aspects of the techniques are directed to transducer excursion correction. A computing device comprising a memory and a processor may be configured to perform the techniques. The memory may store voltage measurements representative of voltage across a transducer and current measurements representative of current through the transducer. The processor may identify a first voltage measurement of the voltage measurements and a first current measurement of the current measurements associated with nonlinear vibration of the transducer. The processor may perform a principal component analysis with respect to the first voltage measurement and the first current measurement to obtain a principal component representative of variation of the voltage across and the current through the transducer. The processor may modify, based on the principal component, an input voltage to be applied across the transducer to reduce the nonlinear vibration of the transducer.
