Out line This device is temperature control experimental device of temperature, lever, pressure , that are the most mon control subject for water treatment plants, chemical factories and power plants. At the experiment of automatic control, it is very important to keep the balance of system. Automatic control system is posed of control subjects and to keep control device. Especially process control has many control subjects to keep selfbalance, so the experimental results is conducted with balance condition. This experimental device experiments about the relation of input signal and output signal to keep the balance (System characteristics) at the cascade experiment and fixed mand control, also experiments on dynamic characteristic (Balance condition without time variation),static characteristic (Balance condition considerating time variation). And you record the change of control amount which was input handling amount or establishment of characteristic experiment. These typical response can be thought step response . You experiment optimum control experiment , fixing P . I. D constant of control device , relating this step response. 2. Process control Process control keeps the balance of the system, automatically correcting toward deviation, and pares every variable to operating toward deviation, and pares every variable to operation condition of industrial process of flux, temperature, surface, pressure, etc with the established goal. Process control is decided into closed loop and Open loop
