Abstract— The main aim of this study was to control the nonlinear process using multi-model PI controller. A multi model is developed for conical tank and it is validated against the real time setup conical tank process. A Multi model based PI controller is also developed, and implemented with realtime setup, and their performances are compared with that of the conventional controller of real t...

Frequency stability of microgrids under islanded operation attracts particular attention recently. A new cooperative frequency control strategy based on centralized multi-agent system (CMAS) is proposed in this study. Based on this strategy, agents sent data and furthermore each component has its own to center operating decisions (MGCC).After deciding on the information, they are returned. Freq...

The objective is to design a model based controller for a small radio-controlled helicopter in hover. To this end, a multi-input multi-output state-space model is identiied from experimental data using linear estimation. A stabilizing H1 controller with setpoint tracking is designed and is compared to a standard LQG controller.

The article focuses on the issues of Load Frequency Control (LFC) under non-linear strategies in multi source multi area hydro thermal system. On practical perspective dead band, boiler dynamics, reheat steam turbine along with hydro turbine operating under two different area capacities are considered in the system. When subjected to random load variations in both the areas, the system exhibits...

Abstract Modern electrical power system design will increase renewable energy sources (RES) dominance. Rotating masses, the main source of inertia in systems, have been greatly decreased producing systems. Thus, load–frequency equilibrium is an important indicator these systems' performance and safety. This work introduces a fractional‐order (FO) operator‐based cascade control structure for isl...

In this paper, the modified linearized Phillips-Heffron model is utilized to theoretically analyze asingle-machine infinite-bus (SMIB) installed with SSSC. Then, the results of this analysis are used forassessing the potential of an SSSC supplementary controller to improve the dynamic stability of apower system. This is carried out by measuring the electromechanical controllability through sing...

In this paper, a robust adaptive actuator failure compensation control scheme is proposed for a class of multi input multi output linear systems with unknown time-varying state delay and in the presence of unknown actuator failures and external disturbance. The adaptive controller structure is designed based on the SPR-Lyapunov approach to achieve the control objective under the specific assump...

Practical complex control problems are often solved using multiple control algorithms. In such cases a complex problem is divided into smaller simpler problems for which separate local controllers can be developed. These local controllers may work together to solve the complete problem. Multi Agentbased Controllers (MAC) are based on this idea. To aid in the design of Multi Agent-based Control ...
