In week 2, we learn about control system. in this section we leard 2 kind of kontrol system.

1. open loop

An open-loop controller, also called a non-feedback controller, is a type of controller that computes its input into a system using only the current state and its model of the system.

A characteristic of the open-loop controller is that it does not use feedback to determine if its output has achieved the desired goal of the input. This means that the system does not observe the output of the processes that it is controlling. Consequently, a true open-loop system can not engage in machine learning and also cannot correct any errors that it could make. It also may not compensate for disturbances in the system An open-loop controller, also called a non-feedback controller, is a type of controller that computes its input into a system using only the current state and its model of the system.

formula is : C(s) = G(s) * R(s)

if the system get there is a change, so the formula become to :

C(s) + ΔC(s) = {G(s) + ΔG(s)}* R(s)

C(s) + ΔC(s)= {G(s) * R(s)}+{ΔG(s)* R(s)}

if there is a change to the C(s) then will ΔC(s) change by the same amount.

On September 1st, 2016, the beginning of the lecture begins at precisely in TC PENS floor 3. The course is taught the Intelligent control by Mr. Son Kuswadi.The first discussion at the beginning of the lecture was to discuss about the lecture system to be applied to our class, and eventually established to implement callenge based learning. The concept is to apply activity of students in the lecture, more material is presented. After that continues to explain the material on adaptive control.Why use the adaptive control? because to achieve the set points, and to get an error as small as possible. After discussing the adaptive control up to the characteristic equation, the system will be stable if the roots of the equation is negative.A system is said to be unstable if the response to an input generate oscillations hard or vibrate at an amplitude / specific price. Instead of a system is called stable if the system will remain in a state of silence.The disruption is part of the system that is made, for example, there is a reservoir used for flood rice fields around, the reservoir should be kept ketinggiannnya not to exceed 10 m, for it takes a resistor so that the reservoir can be terisis as desired.
