An in-wheel motor electric vehicle has high unsprung mass because of its in-wheel motor, which decreases vehicle ride comfort and vehicle safety. This paper presents a controllable suspension employing an optimal design hybrid damping control strategy based on ideal skyhook and groundhook as a reference. A sliding mode controller is designed to make the plant track the ideal reference model. Th...

This paper demonstrates the potential of applying PDlike fuzzy logic controller for active vibration control of piezoelectric Stewart platforms. Through simulation, the control authority of the piezo stack actuators for effectively damping the Stewart platform vibration can be evaluated for further implementation of the system. Each leg of the piezoelectric Stewart platform consists of a linear...

The paper deals with the design and tuning of the PID controller for the closed loop control of the system with modes of different dynamics and different damping. The influence of the chosen controller on the properties of the controlled system is shown using the critical gain and step responses. The use of the presented rules is demonstrated on the tuning of the controller for the position con...

This paper combines the use of the Harris index and the relative damping index (RDI) to give a new method for CPM-based controller tuning. The RDI is defined based on the disturbance impulse response, which is calculated as a byproduct of the Harris index. The proposed technique provides controller settings that attain the best-achievable performance by careful and systematical changing of cont...

This paper proposes a single-loop repetitive voltage control strategy which incorporates the active damping control feature for single-phase uninterruptible power supply (UPS) applications. The proposed method reduces the effect of the LC resonant peak, which limits the control bandwidth and deteriorates the stability of the entire control loop by effectively increasing the damping component. D...

Abstract— This paper presents the model of a static VAR compensator (SVC) which is controlled externally by a Proportional Integral Differential (PID) controller for the improvements of voltage stability and damping effect of an on line power system. The PID controller parameters has been selected by using Ziegler-Nichols tuning rule method. Both single phase and three phase faults have been co...

In this paper a new optimization algorithm, the biogeography based optimization (BBO) is employed to design a robust power oscillation damping (POD) controller using unified power flow controller (UPFC). The controller that is used to damp low frequency oscillation is designed over a wide range of operating points using two different objective functions. The obtained controllers are then verifi...

This paper deals with the modelling and control of semi-batch reactor used for chromium sludge regeneration process. A comparison of three process control approaches is presented. Usual PID controller without online identification (OI) and adaptive PID controller were adapted to semi-batch rector process in our previous studies. In this study the two-degrees-of-freedom (2DOF) controller is deve...
