The sensorless model predictive force control (SMPFC) is a strong method for controlling the drives of three-phase 4(6)-switch inverter linear induction motors. This kind of inverter can be employed for fault tolerant control in order to solve the problem of open/short circuit in 6-switch inverters (B6). This paper proposed a method for the SMPFC of a linear induction motor (LIM) with a 4-switc...

Motion control systems represent a main subsystem for majority of processing systems that can be found in the industrial sector. These systems are concerned with the actuation of all devices in the manufacturing process such as machines, robots, conveyor systems and pick and place mechanisms such that they satisfy certain motion requirements, e.g., the pre specified reference trajectories are f...

In this paper, a robust sliding mode prediction model is combined with a sliding mode voltage model observer to achieve a sensorless predictive torque control method. In order to compensate the uncertainties of the stator and rotor resistances and the offset of measured current, sliding mode feedbacks were added to the voltage model observer. To reduce the effect of the errors that are injected...

the present sought to draw a comparison between model predictive control performance and two other controllers named simple pi and selective pi in controlling large-scale natural gas transport networks. a nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in simulink® environment of matlab®. control schemes were designed to provide a s...

in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...

Full power rating three-level neutral-point clamped (3L-NPC) back-to-back power converters seem promising for wind turbine systems with high power. Direct Model Predictive Control (DMPC) is an attractive technique, in particular, for multi-level converters. Voltage sensorless control makes the voltage measurements obsolete. This work proposes and verifies an Initial Bias Compensation based Virt...

We propose a model predictive control (MPC) method to compensate for the time-varying phase aberrations in sensorless adaptive optics (AO) system. The approximate point spread function (PSF) of imaging system with diversity is mathematically derived, and its validity verified. proposed MPC, which considers operating limits deformable mirror (DM), computes optimal applied voltage each actuator o...
