“…This three-tank system has different control technologies: PLC, industrial controller and PC with LabVIEW ® . In this case, the PLC controller was used as the DAQ system, and is connected through Ethernet to a LabVIEW ® interface [48], in which the compensator (controller+observer) was implemented. Since the real plant is a complete experimental station, all variables were measured with real sensors, as indicated in Figure 1; hence, the state estimation can be compared to real measurements of the levels in all the tanks.…”

“…Using a manual valve (HV) located in the secondary branch, disturbances to the system are injected at Tank

. In this paper, the input to the system is the flow regulated by the control valve, whereas the output of the system is the level in Tank

(see [ 46 , 47 , 48 ] for further details about the process).…”

This paper addresses the observability analysis and observer design for a nonlinear interacting three-tank system. The plant configuration is first described using the process and instrumentation diagram (P&ID) and a state–space realization is derived; some insights about the behavior of the nonlinear system, considering equilibrium points and the phase portrait are provided. Then, observability in the Hermann–Krener sense is analyzed. A high-gain observer (HGO) is then designed, using the equivalence of the original state–space realization with its observability canonical form, in order to guarantee convergence of the state estimation. The performance was validated through simulation and experiments in a multipurpose plant equipped with real sensors; the HGO response was compared to a Luenberger observer (for a linear approximation of the plant) and the Extended Kalman Filter (for which convergence is not guaranteed), considering nonlinearities, interaction, disturbances and noise. Theoretical and experimental results show that the HGO can provide robust estimation and disturbance rejection, despite the sensitivity of HGOs to noisy variables in processes such as level of liquids.

“…The work conducted in [30] is devoted to an application of the control software for a multipurpose tank system, and also to the development of the inspection techniques to teach the fundamentals of monitoring systems and control engineering. In this case of an experimental study, the flexibility and high level specifications of LabVIEW decided to select it as the monitoring interface, since the main control tasks have been assigned to industrial controllers.…”

In this paper, a unique overview of intelligent machines and mathematical methods designed and developed to measure and to control the water level in industrial or laboratory setups of coupled and cascaded configurations of tanks is made. A systematized and concise overview is made of the mechatronic systems used in the measurement, identification, and control of the water level enumerates, the software used in the associated scientific research, modern techniques and sensors, and mathematical models, as well as analysis and control strategies. The broad overview of applications of the last decade is finalized by a proposition of a control system that is based on a parameter estimation of a new experimental setup, an integral dynamic model of the system, a modern mechatronic machine such as the Watson-Marlow peristaltic pump, the Anderson Negele sensor of level, the NI cRIO-9074 controller, and LabVIEW virtual instrumentation. The results of real experimental tests, exploiting a hybrid proportional control, being improved by a numerically predicted water level, are obtained using a few tools, i.e., the static characteristics, the classical step response, and a new pyramid-shaped step function of a discontinuous path-following reference input, being introduced to evaluate the effectiveness and robustness of the regulation of the level height.

“…Modern education methodologies in engineering promote the active role of students in lab experiences, so they become protagonists in a real active learning environment. 28 For example, simulation- and project-based learning (SBL and PjBL, respectively), and their variants (namely problem- and case-based learning), are being applied in order to allow students to refine their practical skills.…”

Virtual laboratories have been demonstrated to contribute successfully to the theoretical understanding of many important systems theory and automatic control concepts in engineering education. This paper describes the pilot experience on the use of such laboratories as learning tools in introductory systems theory courses at the University of Extremadura during the academic year 2015/2016. The purpose of the present paper is to offer some objective academic evidence for the effectiveness of the use of virtual laboratories to improve learning in laboratory lessons in engineering.
