摘要

本文介绍了一种建立双气缸线性模型的方法。进出气流由两个开/关电磁阀调节。所提出的方法通过使用阀门的开/关时间与单个连续控制输入之间的非线性关系来简化两个开/关电磁阀的处理。这个关系表示一个开环控制,以最大速度给出线性输入/输出响应,并减少死带。为了验证所提出的方法,给出了数值模拟。

Linear Dynamic Model of an On/Off Actuated Pneumatic Cylinder: An Optimization Approach
This paper describes a methodology to construct a linear model of a double pneumatic cylinder. The in and out airflow is regulated by two on/off solenoid valves. The proposed methodology simplifies the handling of the two on/off solenoid valves by using a nonlinear relation between the on/off times of the valves and a single continuous control input. This relation represents an open loop control that gives a linear input/output response with maximum speed, and with reduced dead-band. Numerical simulations are given in order to validate the proposed methodology.
