Analysis and design of control systems via parameter‐based approach

Control laws can be constructed in systems design by introducing parameters to obtain good system performance or robustness. A typical example of such a class approaches is the high-gain approach. In controllers, an introduction parameter results family feedback control laws. Such law given parametrized gain matrix which infinity as introduced its extreme value. approach called parameter-based Another case establish mathematical models some extra parameters. derive model spacecraft unit quaternions are three i, j and k with properties i 2 = − 1 ${i^2} {j^2} {k^2} - 1$ , $ij\; {\rm{\;}}k$ $jk\; {\rm{\;}}i$ $ki\; {\rm{\;}}j$ . This Special Issue aims present recent development analysing designing systems. The theme this special issue divided into parts: Model construction parameters, parametric solutions control-related equations. topic includes 6 papers.
