The PID controller still remains a widely used and very effective means of achieving stability in control systems. Generally, the performance is determined by proportional, integral derivative gains controller. classical techniques: Ziegler-Nichols (ZN) open loop method; ZN closed Chien-Hrones-Reswick (C-H-R) load rejection meta-heuristic technique: fuzzy logic algorithm, are to determine tunin...

This paper tackles the control problem of nonlinear disturbed polynomial systems using formalism output feedback linearization and a subsequent sliding mode design. aims to ensure asymptotic stability an unstable equilibrium point. The class under investigation has equivalent Byrnes–Isidori normal form, which reveals stable zero dynamics. For case modeling uncertainties and/or process dynamic d...

diabetes is considered as a global affecting disease with an increasing contribution to both mortality rate and cost damage in the society. therefore, tight control of blood glucose levels has gained significant attention over the decades. this paper proposes a method for blood glucose level regulation in type 1 diabetics. the control strategy is based on combining the fuzzy logic theory and si...
