Most countries are facing a multiplicity of challenges directly related to the pr ent ways in which they currently generate and use energy. Human-induced climate change, rising pollution levels, decreasing energy security, and resource wars are all increasingly linked to the widespread use of non-renewable sources of energy. These interrelated challenges present an ongoing and pressing policy-making dilemma to develop and implement sound energy solutions. Evidence regarding the imperative need for creative energy solutions is amassing a variety of reputable sources. The Fourth Assessment Report by the Intergovernmental Panel on Climate Chance (IPCC) ranks amongst the most salient of these sources. This IPCC report clearly points out that drastic reductions in the use of fossil fuel use are essential to reduce greenhouse gas (GHG) emissions to thereby minimize the most detrimental impacts of climate change.

This paper deals with analysis of main functional diagrams of step PID controllers for electric motor-driven actuators. The main formulae to calculate the parameters of the diagrams of step PID controllers are presented in the paper. The influence of these parameters on the transient processes in step controllers and on the output position of the actuator is analyzed. Transient processes in step controllers with motor-driven actuators are simulated in PI and PID control mode. These transient processes are compared to the transient processes in continuous controllers. The accuracy of step PID controllers is analyzed, and restrictions on the parameters of step PID controllers are presented. The diagrams of step PID controllers considered in this paper can be implemented in the up-to-date PLCs software for automatic control using the electric motor-driven actuators in the control loops.
