+# Общее задание #
+1. Написать отчет по выполненной лабораторной работе №1 в .md формате (readme.md) и с помощью запроса на внесение изменений (**pull request**) разместить его в следующем каталоге: **trunk\ii0xxyy\task_01\doc** (где **xx** - номер группы, **yy** - номер студента, например **ii02102**).
+2. Исходный код написанной программы разместить в каталоге: **trunk\ii0xxyy\task_01\src**.
+
+## Task 1. Modeling controlled object ##
+Let's get some object to be controlled. We want to control its temperature, which can be described by this differential equation:
+
+$$\Large\frac{dy(\tau)}{d\tau}=\frac{u(\tau)}{C}+\frac{Y_0-y(\tau)}{RC} $$ (1)
+
+where $\tau$ – time; $y(\tau)$ – input temperature; $u(\tau)$ – input warm; $Y_0$ – room temperature; $C,RC$ – some constants.
+
+After transformation we get these linear (2) and nonlinear (3) models:
+
+$$\Large y_{\tau+1}=ay_{\tau}+bu_{\tau}$$ (2)
+$$\Large y_{\tau+1}=ay_{\tau}-by_{\tau-1}^2+cu_{\tau}+d\sin(u_{\tau-1})$$ (3)
+
+where $\tau$ – time discrete moments ($1,2,3{\dots}n$); $a,b,c,d$ – some constants.
+
+Task is to write program (**C++**), which simulates this object temperature.
