Adaptive optics (AO) has become an indispensable tool for ground-based telescopes to mitigate atmospheric seeing and obtain high angular resolution observations. Predictive control aims overcome latency in AO systems: the inevitable time delay between wavefront measurement correction. A current method of predictive uses empirical orthogonal functions (EOFs) framework borrowed from weather predi...

This paper presents a novel approach to introducing adaptation in Model Predictive Control (MPC). Assuming limited priori knowledge about the process, we consider finite set of possible models (a dictionary), and use theory adversarial multi-armed bandits develop an adaptive version MPC called (AAMPC). Under weak assumptions on dictionary components, then establish theoretical bounds performanc...

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...

A modified method for satellite attitude control system in presence of novel actuators is proposed in this paper. The attitude control system is composed of three fluidic momentum controller (FMC) actuators that are used to control Euler angles and their dynamics is considered in satellite attitude equations as well. L1 adaptive control is utilized for satellite three-axial ...
