In this paper, a mathematical modeling of pneumatic actuator system is developed by using RLS algorithm. An ARX model is chosen for the model structure. In order to cater the time-varying parameter of pneumatic system, a self-tuning controller is implemented based on the pole-assignment controller. An online RLS algorithm update the parameter estimation at every sample interval. The pole-assignment control parameter is then updated accordingly to the changes of the system parameters. Result of the system performance is compared with the conventional PID controller optimized by PSO algorithm. It is observed that the self-tuning controller performed well with almost zero error at steady state condition and overshoot less than 1%.

This paper presents the design of a H∞ current controller for doubly fed induction generators (DFIGs) in order to maintain stable operation under unbalanced voltage conditions. The H∞ current controller has a multi-input and multi-output (MIMO) structure and is designed using the loop shaping method. Case studies have been carried out in order to verify the efficacy of the proposed H∞ current controller for DFIGs. The case study results show that the proposed H ∞ current controller can realize different control objectives, i.e. stable stator current, stable stator active power and stable stator reactive power. It is also shown that the H ∞ current controller is less sensitive to the parameter perturbation.

This paper presents the design of two controllers namely, Direct Fuzzy Logic controller and Fuzzy Model Reference Learning control applied to a new aerial manipulation system called "Quadrotor-Manipulator System". This system consists of 2-link manipulator connected to the bottom of a quadrotor. The dynamic model of this system is derived taking into account the effect of adding a payload to the manipulator. The performance of the proposed controllers are compared with that of the previously developed controller based on Feedback Linearization technique. All controllers are tested regarding their ability to stabilize the system and track desired trajectories under the effects of picking and placing a payload as well as changing the system operating region. Finally, the system equations of motion and the control laws are simulated using MATLAB/SIMULINK. The simulation results indicate the outstanding performance of the Fuzzy Model Reference Learning control.

This paper focuses on the control strategy to be used to parallel hybrid electric vehicles (HEVs). A model-based strategy for the fuel-optimal control is presented. The torque split control problem of the vehicle is formulated as an optimal control of switched system. The optimal control problem of such switched system is formulated into two stage optimization problem. The dynamic programming is utilized to solve the optimal control action that minimizes the cost function. The simulated results indicate that this method is effective to improve the fuel economy. © 2012 IEEE.

This paper proposes a methodology of mechatronics design applied to the concept of a service robot to clean storage tanks. Through this methodology, the system static analysis is done first, followed by dynamic analysis, and finally robot design. In some cases the cleaning process is done manually, but in tall oil tanks, workers need scaffolding or cranes. The principal, most popular cleaning method used is sandblasting, but it can give the workers health problems like acute silicosis. This is why a robot capable of working with sandblasting is proposed, changing the traditional cleaning method and improving the life quality of workers, with reduced cleaning time and improved service quality. © Springer-Verlag Berlin Heidelberg 2012.

In this study interval type-2 fuzzy systems with non-singleton type-2 fuzzifire are used for identification and modeling nonlinear systems having noise with changing domain for fault detection purpose. The main idea in this fault detection method is to serve an upper bound and a lower bound as a confidence bound for system output that obtained from the interval type-2 fuzzy system. If we haven't precise information about mean and variance of noise, then non-singleton type-2 fuzzifire is usable. This fuzzifire improves performance of fault detection confidence bound. In the end of this paper a well-known benchmark two-tank system has been used for representing the advantages of proposed fault detection method.

This paper is concerned with the design of a dynamic multivariable PID control for multi input multi output (MIMO) process. Four multivariable PID control schemes using Davison, Penttinen-Koivo, Maciejowski and a combined method were applied. The controller parameters for all control strategies were designed based on dynamic condition using singularly perturbed system. The purpose of the study is to investigate the effectiveness in the performance of dynamic control based on different multivariable PID control strategies. To attain the best result, numerous tuning parameters were tested. The simulation results show the significance of the study whereby the proposed dynamic MPID control scheme shows better improvement in control tuning of nonlinear system.
