Nowadays, motion control systems in industry are designed with fixed PLrPID cascade control loops. These control loops do not take into account the dynamic load variations that occur in many systems. Therefore, as the dynamics of the process inevitably varies, they fall out of tune, which causes the performance and stability to degrade. Also, time delays often arise in motor control systems, bo...

Many industrial processes are in cascade configuration in which the material being processed goes through a sequence of processing units. In many cases, direct in-process measurements of the relevant variable are not available at all but at the last processing unit. Surrogate or model based soft measurements in which the relevant inprocess variables are inferred from other measurements would be...

In this paper, a clutch actuator system for DCTs is developed by integrating a brushless DC motor with mechanical subsystems. The system modeling is performed with experimental validations. However, since the developed model is based on the linear system, it may include modeling uncertainties and external disturbances. To overcome this difficulty, a cascade control structure is proposed. Theref...

This paper is concerned with finite-time chaos control of unified hyperchaotic systems with multiple parameters. Based on the finite-time stability theory in the cascade-connected systems, a nonlinear control law is presented to achieve finite-time chaos control. The controller is simple and easy to be constructed. Simulation results for Lorenz hyperchaotic system, L ü hyperchaotic system, Chen...

This paper considers employing missile guidance concepts to design motion control systems for marine craft. Initially, classical concepts such as line of sight (LOS), pure pursuit (PP), and constant bearing (CB) are reviewed. Subsequently, the relationship of these concepts to motion camouflage strategies in nature is pointed out, as well as their application to robot manipulators. Ultimately, ...

Feedback circuits in biochemical networks which underly cellular signaling pathways are important elements in creating complex behavior. A specific aspect thereof is how stability of equilibrium points depends on model parameters. For biochemical networks, which are modelled using many parameters, it is typically very difficult to estimate the influence of parameters on stability. Finding param...
