This paper concerned with different control strategies used to balance (control) inverted pendulum system. The often used control strategy is PID tuning, but in PID the main issue is parameter tuning according to the process parameter variation. So proposed strategy is MRAC, combination of model reference adaptive Control (MRAC) with fuzzy. The main aim is to find further improvement of traditional MRAC method and to provide more accurate control to the inverted pendulum and to minimize drawbacks of the traditional MRAC method. This is examined when combining the MRAC method with Fuzzy control. The performance of the application system is examined from the simulation results in MATLAB/SIMULINK. For showing its effectiveness, simulated results are compared with the traditional control strategies like fuzzy and MRAC. Incorporating application for inverted pendulum system, subjected to it finds the analogy with various control system applications like satellite launching system, robotic arm etc.

Summary Satisfactory performance of doubly fed induction generator (DFIG) is indebted to determining the proportional‐integral (PI) gains of the power electronic converter controls as accurate as possible to guarantee minimum transients when disturbances occurred in the power system. Since the DFIG is introduced as a dynamical system, PI gains must be changed according to the system requirements. Fuzzy controllers designed based on our best knowledge on the system behavior are able to continuously adjust parameters of the control system to enhance the performance of the system. In this paper, a control scheme based on self‐tuning fuzzy PI (STFPI) is proposed to control the power electronic converters of the DFIG. Different arrangements of the STFPI controller are considered in the control scheme of active and reactive power. The performances of the DFIG in three operating modes are compared when the STFPI and the conventional PI are installed and the system experiences a single phase to ground short circuit fault. Super‐synchronous, synchronous, and sub‐synchronous operating modes are examined in the paper. The idea is implemented on a study system equipped with a DFIG wind turbine, and the obtained results show that when the proposed scheme is employed a superior performance can be achieved in transient conditions and the transients are significantly improved.

A novel design procedure of internal model controller based on the Double-Decomposition (DD), which includes the Full Rank Decomposition (FRD) and Singular Value Decomposition (SVD), is proposed for the multivariable system with multiple time-delay plant. In the controller design process, the Reflexive Generalised Inverse Matrix (RGIM) based on FRD is used to replace the generalised inverse matrix to design the internal model controller; improved filter based on SVD is introduced into the design process. In the FRD process for a non-square system, the Effective Relative Gain Array (ERGA) is applied to select the linear independent column. After model reduction for the internal model controller, the expression of the controller is obtained. Then the square system and the non-square system are taken as examples. The simulation results show the effectiveness of the proposed approach for the multivariable system with the multiple time-delay plant.
