Popis: | The sliding-mode control (SMC) has been used successfully to stabilize nonlinear systems, yet a side effect of SMC is chattering, an undesired phenomenon. Researchers have then introduced the so called integral-type approach to diminish chattering. Additional studies have shown that SMC with the socalled barrier function can drive the system state to a region close to the origin. The main contribution of this paper is to join both setups in the context of SMC, i.e., integral term and barrier function. We show that SMC with both integral term and barrier function can be used to track any given trajectory while ensuring both stability and chattering-free performance. The potential of this novel control for applications is illustrated through real-time experiments performed on a magnetic levitation system. |
