摘要

This paper presents an analysis and comparison of three control strategies designed for systems with inverse response characteristics and variable reference tracking. Dynamic Sliding-Mode Control (DSMC), Sliding-Mode Control (SMC), and Proportional-Integral-Derivative (PID) control. The efficacy of these controllers was assessed using simulations in a nonlinear isothermal Continuous-Stirred Tank Reactor (CSTR) and through tests in a modified Temperature Control Lab (TCLab). The results from both simulations and experiments reveal that DSMC consistently exceeds SMC and PID controllers in tracking performance to manage the inverse response when the reference varies.
