This paper presents the experimental validation of an active control approach to improve the damping of a spindle system for wood machining. The active control was implemented using piezoelectric actuators in push–pull configuration with real-time control capabilities. The adaptive control strategy based on the linear quadratic Gaussian is first modeled within MATLAB/Simulink and then implemented on the real spindle system. Experimental tests were performed on the small-scale planer prototype to validate the simulation models. Moreover a cutting force observer which can be used to continuously monitor the cutting process is also implemented and its performance is presented.

Abstract

This paper presents the experimental validation of an active control approach to improve the damping of a spindle system for wood machining. The active control was implemented using piezoelectric actuators in push–pull configuration with real-time control capabilities. The adaptive control strategy based on the linear quadratic Gaussian is first modeled within MATLAB/Simulink and then implemented on the real spindle system. Experimental tests were performed on the small-scale planer prototype to validate the simulation models. Moreover a cutting force observer which can be used to continuously monitor the cutting process is also implemented and its performance is presented.
