Designing the controller for the control of cardiac pacemakers to maintain the heart rate in a efficient way is very challenging. Proportional - Integral - Derivative control schemes continue to provide the simplest and effective solutions to most of the control engineering applications today. However, tuning of these controllers is time consuming, not easy and generally lead to poor performance especially with non-linear systems. This paper presents a Bioinspired optimization (BIO) algorithm for tuning the (PID) controller parameters for the control of pacemaker. This approach has superior features, including easy implementation, stable convergence characteristic and good computational efficiency over the conventional methods. The PID conventional controller had been applied and results were compared with the automatic tuning BIO-PID for the pacemaker using Matlab coding .The proposed algorithm is used to tune the PID parameters and its performance has been compared with the conventional Ziegler Nichols method. The results obtained reflects that use of heuristic algorithm based controller improves the performance of pacemaker in terms of time domain specifications, set point tracking and regulatory changes and also provides an optimum stability. This paper discusses in detail, the Bioinspired technique and its implementation with PID tuning for a controller of a pacemaker. Compared to other conventional PID tuning methods, the result shows that better performance can be achieved with the soft computing based tuning method. The ability of the designed controller in terms, of tracking set point is also compared and simulation results are discussed.
