Since straightness error of linear motor stage is hardly dependent upon machining accuracy and assembling accuracy, there is limit on maximum realizable accuracy. To cope with this limitation, this paper proposed a servo system to compensate straightness error of a linear motor stage. The servo system is mounted on the slider of the linear motor stage and moves in the direction of the straightn...

Linear motor is one of the most important drive units for high-speed machining centers. Nonlinear friction is an important factor affecting the positioning accuracy of linear motor drive system. One of the most important topics for controlling linear motor is how to accurately estimate the parameters of the friction and effectively compensate it. In this paper, to solve the problem existing in ...

Neural decoding of motor control of hand and arm movements in primates is a challenging task that requires developing statistical models that explain how the recorded neural population activity relates to motor behavior. Until recently, much of the work in this area has focused on learning linear models of decoding for low-dimensional motor control, such as 2D control of a computer cursor. Capt...

Permanent magnet synchronous motor (PMSM), employing vector control, is used in high performance servo drive applications. It is highly non-linear plant which can be described by linear parameter varying (LPV) state-space model. In order to solve nonlinearity problem and syntesize speed controler, tensor product (TP) model transformation is proposed. Using this transformation, given linear para...

The paper describes design and optimisation of a tubular moving-iron linear permanent magnet motor for reciprocating compressor using finite element. The four leading design parameters are optimised individually. To validate the process reaches an optimal design, two leading parameters are varied simultaneously. This is due to one parameter may influence other parameters. The linear motor is ai...
