Design of PID Controller with Filter for Distributed Parameter Systems

摘要: Abstract This paper presents a method for tuning simple controllers distributed parameter systems in the process industry. These are usually described by partial differential equations (PDE), which then simplified into lumped represented ordinary (ODE), providing low order transfer functions used PID control design. The drawback of this approach is that system only performs well at bandwidths and without disturbances, as relevant dynamics, such resonances lying medium-high frequencies, not taken account, limiting performance closed-loop system. work proposes SISO uses function models (obtained directly from PDE) to tune controller incorporates filter designed fulfill requirements.
