Observer based controllers for loop transfer recovery of non-strictly proper systems which are left invertible and of minimum phase are considered. A complete analysis of loop transfer recovery problem using either full or reduced order observer based controller is provided. Key Words-Robust control, loop transfer recovery.

−In the paper you will implement a set point control system for the single-link manipulator with flexible joint using a multiloop controller based on feedback linearization (inner loop) and linear statefeedback control (outer loop). Then, you will modify the multiloop controller to solve a trajectory tracking problem. The simulations demonstrate that the multi-loop control law it is a viable me...

in general, the objective of distillation control is to maintain the desired products quality. in this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. these methods are: a) composition control using measured composition directly. this method sufferes from large sampling delay of measuring device...

For this feedback loop to be stable, negative feedback is used. This means that the output voltage (VOUT) is compared to the reference voltage (VR) and the difference (VR – VOUT) is amplified by the error amplifier. The output of the error amplifier is called the error voltage. The error voltage polarity is inverted with respect to VOUT and is therefore -180° out of phase with VOUT. The goal of...

We present a system for large scale robotic learning from demonstration. We describe a set of software tools for enabling human-robot interaction over the internet and gathering the large datasets that such crowdsourcing makes possible. We show results in which humans teach a robot to navigate a maze over the Internet. Robots occupy a peculiar place in our culture. We have been building robots ...

In this paper, an efficient method is presented to control the attitude of a satellite with ON-OFF actuator. The main objective of this novel method is to control the amplitude of the limit cycle which commonly appears in the steady state of such systems; and at the same time by consideration of real actuator constraints, reduce the fuel consumption of system. The Proposed method is a combinati...
