摘要
步进梁是加热炉中的重要设备,步进梁的速度须精准控制,否则易对步进梁造成很大的惯性冲击。由于步进梁系统是典型的非线性和时变性系统,且当步进梁托起钢坯时速度会大幅度下降,严重影响步进梁的速度,鉴于此建立了步进梁系统的传递函数,提出了模糊PID的控制策略,理论上能够较好地满足控制要求。仿真结果表明,所提出的控制算法具有结构简单、抗干扰、响应快等特点。
Walking beam is an important equipment in furnace. The speed of the walking beam should be precisely controlled, otherwise it easily causes a great inertial impact on the walking beam. Walking beam system is a typical nonlinear and time-varying system, and when the walking beam billet holds billet, the speed of the walking beam will be a significant decline, seriously affecting the control accuracy of the walking beam. For this, the paper establishes the transfer function of the walking beam system, and puts forward a fuzzy PID control strategy which can better meet the control requirements in theory. Simulation results show that the proposed control algorithm has the characteristics of a simple structure, interference and fast response.
