Control Definition and 1000 Threads

Can anyone provide some introductory links of Model Predictive control Thank You, Yaswanth

I am modelling the vibration of a 2 D.O.F system with damping in Simulink. I want to set up control such that if the control value is between two values (max and min) then it sets the control value to the specified input but if it is outside the max and min interval then the control value is...

Hi guys, my first post on these forums. I am learning electronics and am still very new to this all. My current tinker project is to learn how regular tv remote controls work. So far I have understood that the remote sends blinking IR pulses through an 940 nm LED. The remote uses...

Last year I built an electric car. I converted a 1966 MG to electric using 8 led acid batteries (96V bus), a DC motor coupled to the transmission, and a large motor controller. The vehicle was working fine. Top speeds of 55 mpg, but with many led acid vehicles, only a 20 miles range. The DC...

Hello. I know that control rods in reactors work by absorbing neutrons that would otherwise be used to collide with say, Uranium, to cause fission. But here is the part I do not understand: As far as I understand, a Uranium atom fissions because it absorbs a neutron causing it to become...

I am in the early stages of the design of a telescope mount and I need a control motor. I am hoping to run it on a battery so I think a DC motor is the way to go, but I need to be able to keep the rotation speed extremely constant for photographic purposes. So, to my question: Does anyone...
