    <briefdescription>
<para>A second-order control loop implementation class. </para>
    </briefdescription>
    <detaileddescription>
<para>This class implements a second order control loop and is intended to act as a parent class to blocks which need a control loop (e.g., <ref refid="classgr_1_1digital_1_1costas__loop__cc" kindref="compound">gr::digital::costas_loop_cc</ref>, <ref refid="classgr_1_1analog_1_1pll__refout__cc" kindref="compound">gr::analog::pll_refout_cc</ref>, etc.). It takes in a loop bandwidth as well as a max and min frequency and provides the functions that control the update of the loop.</para>
<para>The loop works of alpha and beta gains. These gains are calculated using the input loop bandwidth and a pre-set damping factor. The damping factor can be changed using the <ref refid="classgr_1_1blocks_1_1control__loop_1abb3497f1bbae1f1835808e80e8d5d24f" kindref="member">set_damping_factor</ref> after the block is constructed. The alpha and beta values can be set using their respective <ref refid="classgr_1_1blocks_1_1control__loop_1a96941dd371da64d83e3c3f8eab7bfc8a" kindref="member">set_alpha</ref> or <ref refid="classgr_1_1blocks_1_1control__loop_1a1bb58989ff0c57cf2cc90d0804788f6f" kindref="member">set_beta</ref> functions if very precise control over these is required.</para>
<para>The class tracks both phase and frequency of a signal based on an error signal. The error calculation is unique for each algorithm and is calculated externally and passed to the advance_loop function, which uses this to update its phase and frequency estimates.</para>
<para>This class also provides the functions <ref refid="classgr_1_1blocks_1_1control__loop_1a410bd28032522a9ea3357e1760b8846b" kindref="member">phase_wrap</ref> and <ref refid="classgr_1_1blocks_1_1control__loop_1a31b65cd76562c7ba387ceee475d3b102" kindref="member">frequency_limit</ref> to easily keep the phase and frequency estimates within our set bounds (phase_wrap keeps it within +/-2pi). </para>
