Abstract

This paper presents a simplified digital control for a feed drive system. The feed drive system generally includes uncertainties and nonlinearities which result from inertia of loads, friction and so on. Thus, it is difficult to ensure robust performance and high accuracy for motion control. In this paper, both pole placement control and adaptive control systems are designed based on a novel discrete-time model of the feed drive system to overcome the above stated problem. This model is characterized with its simple structure reducing number of parameters and regarding no nonlinear terms and disturbances. Therefore, the digital control systems can be simplified in design and algorithm calculation. Experimental results have shown high performance and effectiveness of the proposed method.
