Improved constrained cascade control for parallel processes

Static and low order anti-windup synthesis for cascade control systems with actuator saturation: An application to temperature-based process control

“…In Appendix C, it is shown that the objective function (19) ensures internal stability, well-posedness and that L 2 gain from u lin to weighted vector of y d1 and y d2 less than γ . By using the relations for y d1 , y d2 ,ẋ 1 andẋ 2 from (14) and putting them into the objective function (19), we get the inequality in Box II. Sector boundedness (7) can be written as:…”

“…We use the following cascade plants and controllers [19] to show the results of proposed methodology and its comparison with the results of traditional MIMO AWC methodology.…”

Process control through a case study: A mixing process. I. SISO case

“…The constraint on the tank's level can be achieved at the expense of the product's consistency using the water valve as the actuator. The basic control structure used, as proposed in [20], is illustrated in Figure 10. Figure 6 System response to a step change in furnish flow from 75% to 60% using PI and feedforward.…”

Development of a DC-link protection system for regenerative braking of Electric Vehicle using a pseudo-cascade controlled IGBT chopper

“…The proposed dissipating system allows maximum braking capacity and maximum battery charging efficiency while still protecting the battery against surge line charging current and overvoltage. To do so, the proposed system use a digital pseudo-cascade control structure [7] implemented in a NI CompactRIO module interfacing with LabVIEW. The use of a pseudo-cascade structure allows the capability to constraint the battery charging current and the DC-link voltage using only a single switching device by giving a priority to the current loop.…”
