In this paper, the possibility of Multi-Input Single-Output control of the heat distribution processes is investigated. Based on the validated model of the example experimental setup, the static and dynamical properties of the process are investigated and discussed in terms of control performance and efficiency. Two potential manipulating variables are considered and different control strategies are...
In this paper, the practical verification of Active Disturbance Rejection Controller (ADRC) implementation for pneumatic setup is investigated. Apart from experimental results, the inverse half-rule is suggested to support ADRC tuning for the second order processes by adjusting the value of the scaling factor. This rule is based only on the approximation of the process step response by First Order...
In this paper, the robust tuning method for FirstOrder Active Disturbance Rejection Control based on Reduced-Order Extended State Observer is proposed. Its robustness is ensured by defining gain margin and phase margin constraints and then, for these constraints, the optimal load disturbance rejection is ensured by suggested tuning method in terms of optimal Integral Absolute Error. The D-partition...
This paper concentrates on the possibilities of the application of the virtual commissioning procedure for the design and verification of the control systems for the continuous industrial processes. After short review and defining the motivation and recognizing the bottlenecks, the case study is presented. It is based on the laboratory pneumatic setup representing the nonlinear continuous process...
In this paper, the potential possibilities of robust tuning of the Balance-Based Adaptive Controller (B-BAC) are discussed in terms of user-defined gain and phase margins. Considering the First Order + Dead Time (FOPDT) process to be controlled and starting from previously suggested simple B-BAC tuning method, the additional tuning parameter is introduced and its influence on the stability boundaries...
This paper describes the stage of initial validation of the model-based control of the plate heat exchanger (PHE) by simulation. For the distributed parameter model of PHE validated on the basis of the measurement data collected from the real process, the approximation by the orthogonal collocation method is applied and then the linearizing controller with the on-line compensation for the potential...
This work shows the results of the practical implementation of the linearizing controller for the example laboratory pneumatic process of the third relative degree. Controller design is based on the Lie algebra framework but in contrast to the previous attempts, the on-line model update method is suggested to ensure offset-free control. The paper details the proposed concept and reports the experiences...
In this paper, the simplified modeling of the counter-flow plate heat exchanger is presented. The aim of the work is to propose a relatively simple model useful for the controller design. Dynamical behavior of the plate heat exchanger is modeled by simple double pipe model. Two different methods are used to approximate the partial differential equations. The first one is the finite difference method...
In this paper, the cascade control of the supply system for the heat exchanger is presented. The aim of the work is the construction of cascade control system, when the output for the inner loop is not measurable. This signal is reconstructed by using the state observer derived from the distributed parameter model of the heat transportation and its implementation is based on the orthogonal collocation...
