What is the difference among complete combustion,incomplete combustion,and controlled combustion of alkanes?

The oxidation of alkanes can be classified into three types based on the conditions:
$1$. Complete Combustion:
- It occurs in the presence of excess air or $O_2$.
- The main products are $CO_2$ and $H_2O$.
$2$. Incomplete Combustion:
- It occurs in the presence of a limited supply of $O_2$.
- The main products are $CO$ and $H_2$. However,for $CH_4$,carbon black $(C_{(s)})$ and $H_2O$ can also be obtained.
$3$. Controlled Combustion:
- It is performed in the presence of $O_2$ and specific catalysts.
- The products formed depend on the catalyst used and the reaction conditions.
