A tuning procedure of the super-twisting algorithm is exploited in order to operate a thermal plant within predefined specifications. The configuration consisting of the chosen control algorithm and the thermal plant results in a limit cycle, i.e. the solutions of the closed-loop system are periodic functions of time. The tuning algorithm is based on the pre-specified amplitude and frequency of the variable to be controlled. The computation of the constant controller gains is based on the equation of harmonic balance. A possibly needed dynamical filter is introduced to guarantee that every desired amplitude and frequency of the limit cycle can be adjusted. The tuning procedure is extended such that the controller parameters can be calculated directly without using any graphical aids. Real world experiments demonstrate the achieved accuracy of the tuning algorithm
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
