<p>Intelligent control can be divided into the following major sub-domains:

<ul><li><a href="Artificial_neural_network" class="mw-redirect" title="Artificial neural network">Neural network</a> control</li>
<li><a href="Machine_learning_control" title="Machine learning control">Machine learning control</a></li>

<p>New control techniques are created continuously as new models of intelligent behavior are created and computational methods developed to support them.

<div class="mw-heading mw-heading3"><h3 id="Neural_network_controller">Neural network controller</h3></div>
<p><a href="Artificial_neural_network" class="mw-redirect" title="Artificial neural network">Neural networks</a> have been used to solve problems in almost all spheres of science and technology. Neural network control basically involves two steps:
</p>
<ul><li>System identification</li>
<li>Control</li></ul>
<p>It has been shown that a <a href="Feed_forward_(control)" title="Feed forward (control)">feedforward</a> network with nonlinear, continuous and differentiable activation functions have <a href="Universal_approximation_theorem" title="Universal approximation theorem">universal approximation</a> capability. <a href="Recurrent_neural_network" title="Recurrent neural network">Recurrent</a> networks have also been used for system identification. Given, a set of input-output data pairs, system identification aims to form a mapping among these data pairs. Such a network is supposed to capture the dynamics of a system. For the control part, deep <a href="Reinforcement_learning" title="Reinforcement learning">reinforcement learning</a> has shown its ability to control complex systems.
</p>
<div class="mw-heading mw-heading3"><h3 id="Bayesian_controllers">Bayesian controllers</h3></div>
<p><a href="Bayesian_probability" title="Bayesian probability">Bayesian probability</a> has produced a number of algorithms that are in common use in many advanced control systems, serving as <a href="State_space_(controls)" class="mw-redirect" title="State space (controls)">state space</a> <a href="Estimator" title="Estimator">estimators</a> of some variables that are used in the controller.
</p><p>The <a href="Kalman_filter" title="Kalman filter">Kalman filter</a> and the <a href="Particle_filter" title="Particle filter">Particle filter</a> are two examples of popular Bayesian control components. The Bayesian approach to controller design often requires an important effort in deriving the so-called system model and measurement model, which are the mathematical relationships linking the state variables to the sensor measurements available in the controlled system. In this respect, it is very closely linked to the
<a href="Systems_theory" title="Systems theory">system-theoretic approach</a> to <a href="Control_engineering" title="Control engineering">control design</a>.
