“…It was shown that the passivity-based controller design strategy could suppress all elastic vibration modes and it didn't need any model reduction. Similar work has also been done by Namerikawa and Kawano (2006), in which a passivity-based controller was designed to stabilize the iron ball suspension system. The experiments showed that the passivity-based controller achieved better performance than the conventional PID controller.…”

The coupled resonance that occurs between a maglev vehicle and an elevated bridge is a unique problem for an electromagnetic suspension maglev system when the vehicle is suspended above the bridge without moving. This problem causes the bridge to vibrate in a large amplitude, it significantly degrades the ride comfort of the maglev train, and it needs to be solved before the commercial application of the system. In this paper, the principle of the stationary vehicle–bridge coupled resonance is investigated, and it is shown that the levitation system is non-passive and it causes self-excited vibration when the first resonance frequency of the bridge approaches the critical frequency of the levitation system. To eliminate the coupled resonance, an approach using a tuned mass damper (TMD) to render passive the levitation control system is presented, and it shows that a TMD with appropriate parameters can stabilize the coupled system. A procedure for seeking out a group of suboptimal parameters of the TMD is also proposed. This procedure ensures that the designed result has a satisfactory performance as well as a reasonable stability margin. The location where the TMD should be mounted to achieve the best performance is discussed. The numerical simulation shows that the designed TMD can completely suppress the vehicle–bridge coupled resonance.

“…Some authors have proposed nonlinear controllers such as Feedback Linearization [11], Sliding Mode Control (SMC) [12], Backstepping [13], High-Gain Observer [14], and Passivity-Based Control [15]. Nonlinear control has advantages in controlling high nonlinear systems such as this MLBS, but it also has disadvantages.…”

This paper explains the design of Servo State Feedback Controller and Feedback Linearization for Magnetic Levitation Ball System (MLBS). The system uses feedback linearization to change the nonlinear model of magnetic levitation ball system to the linear system. Servo state feedback controller controls the position of the ball. An integrator eliminates the steady state error in servo state feedback controller. The parameter of integral gain and state feedback gains is achieved from the concept of Coefficient Diagram Method (CDM). The CDM requires the controllable canonical form, because of that Matrix Transformation is needed. Hence, feedback linearization is applied first to the MLBS then converted to a controllable form by a transformation matrix. The simulation shows the system can follow the desired position and robust from the position disturbance. The uncertainty parameter of mass, inductance, and resistance of MLBS also being investigated in the simulation. Comparing CDM with another method such as Linear Quadratic Regulator (LQR) and Pole Placement, CDM can give better response, that is no overshoot but a quite fast response. The main advantage of CDM is it has a standard parameter to obtain controller's parameter hence it can avoid trial and error.

“…The single degree-of-freedom (DOF) magnetic levitation system is the most widely studied maglev system because of its simplicity in the dynamic structure. [5][6][7] Many advanced control algorithms have been applied to stabilize 1 DOF maglev system. In Yang et al 5 a controller was designed by a modified backstepping procedure of the conventional Kalman filter approach.…”

Magnetic levitation techniques have been used to eliminate friction due to mechanical contact, decrease the maintaining cost and achieve high-precision positioning. Although there are many studies on the single degree-of-freedom magnetic levitation control algorithms, it is difficult to achieve excellent control performance using classical control methods for the multiple-in-multiple-out magnetic levitation system because of the coupling in the dynamic system and the nonlinearity of the electromagnetic force. This article presents a 3 degrees-of-freedom magnetic suspension stage. At first the dynamic model of the stage is derived; then a nonlinear intelligent decoupling controller is developed to stabilize the levitation system. The control architecture consists of three components: (1) fuzzy sliding mode technique for the uncertainty in the system parameter; (2) force distribution for decoupling; (3) extended state observer for compensating the system disturbance. Finally experiments are designed to verify the effectiveness of the proposed controller. Experimental results show that compared with the classical proportional–integral–derivative controller, the proposed controller provides excellent transient response performance and the system is robust against the parameter uncertainty and external disturbance.
