DCS在控制上的大特点是依靠各种控制、运算模块的灵活组态，可实现多样化的控制策略以满足不同情况下的需要，使得在单元组合仪表实现起来相当繁琐与复杂的命题变得简单。随着企业提出的高柔性、益的要求，以经典控制理论为基础的控制方案已经不能适应，以多变量预测控制为代表的控制策略的提出和成功应用之后，过程控制受到了过程工业界的普遍关注。需要强调的是，广泛应用各种控制与优化技术是挖掘并提升DCS综合性能有效、直接、也是具价值的发展方向。

在实际过程控制系统中，基于PID控制技术的系统占80%以上，PID回路运用优劣在实现装置平稳、、运行中起到举足轻重的作用，各DCS厂商都以此作为抢占市场的有力竞争砝码，开发出各自的PID自整定软件。另外，根据DCS的控制功能，在基本的PID算法基础上，可以开发各种改进算法，以满足实际工业控制现场的各种需要，诸如带死区的PID控制、积分分离的PID控制、微分先行的PID控制、不完全微分的PID控制、具有逻辑选择功能的PID控制等等
