This paper addresses the problem of region tracking control for underwater vehicles without velocity measurement in marine environment. For this case, an improved strategy is proposed based on a Nussbaum-type state observer. In scheme, observer developed to estimate unmeasured vehicle. And then presented by incorporating estimated observer, such that errors satisfy requirement prescribed bounda...

A cascaded deadbeat predictive control strategy with online disturbance compensation is proposed for a three-phase interleaved boost converter in this paper. The topology of the symmetric, so inner loop controller also designed symmetrically. For purpose realizing error-free tracking reference value, method adopted and outer loops Luenberger observers, which are to estimate compensate disturban...

This paper presents an observer-based robust control for mechatronic systems that utilize a surface-mounted permanent magnet synchronous motor (SPMSM). A mechatronics system with SPMSM typically comprises mechanical moving part (outer-loop) and power converter (inner-loop) to drive the motor. We explain dynamic modeling of provide brief discussion on disturbances in SPMSM. cascaded tracking err...
